As a best practice, you should be running AD DS and AD-Integrated DNS zones (ADI zones) on the same server. This is because the DNS records in ADI zones are replicated using AD DS replication and are stored in the directory, rather than using things like a zone transfer to get records across multiple DNS servers. If you want to use ADI zones for your ...

If it's only Active Directory that you want to move then one possible solution can be is to install a secondary Domain Controller(DC) in your VM, transfer all FSMO Roles to the VM and then demote your older DC. Check the following links for step-by-step process Adding a 2012 Domain Controller to an existing Domain Demoting a 2012 Domain Controller ...

There are other good answers to this, but they're fairly theoretical. I thought it might be useful for you to know that I've done this, on a number of occasions, and it's fine, but on CentOS servers using dovecot and sendmail, and I use mbox as a storage format. I know you're using postfix and Maildir, and I'm sorry I can't shed specific light on that; I ...

You should handle that migration at the application level, so that you have a clean start with the new server and no leftover migration cruft (like hypervisor tools and drivers) lying around. Start with a list of all the things the server currently hosts, and migrate those roles individually onto the new server using migration procedures specific to each ...

You will have to test to find out. There are many variables such as the speed of your storage system. Consider restoring your tar archive or backup while the old system is up. Then during the downtime use rsync to copy the remaining changes. It still has to check many file modify times which takes time, but there is much less I/O and network transfer. This ...

While there are tools that can rename a domain, it can be a complicated process. You have a couple options. 1. You can add an alternate UPN so that @domain.com is valid. 2. You can migrate to a new domain. I'd try the upn route first

Rsync may allow you to sync the files without taking the server down. For example, you could do a sync while in production, then take the server down, sync again to make sure you got everything that changed in the mean time, and then turn on the new server. The second sync will be incremental, and would take a fraction of the time of the whole, minimizing ...

Under the configuration settings for the AD domain, you need to make sure that it's configured to allow devices to be joined. There is more information here - https://azure.microsoft.com/en-us/documentation/articles/active-directory-conditional-access-device-registration-overview/?rnd=1

The first answer from jornane is correct so far as it goes, however I do not believe it addresses what the OP is really trying to get at - which is how best to handle migration of email and accounts, rather than how to handle DNS. Ordinarily there are many ways to handle this task, but because we are dealing with only one server which will be going through ...

The answer is yes, and there's no conflicting information. Any person, article or resource that claims this doesn't occur is just plain wrong. The linked article explains the process. This has not changed from Windows 2000 and carries forward all the way through Windows Server 2012 R2. Make note of these sections: The transfer of an FSMO role is the ...

Your DNS TTL on your address record is set to 86400 (seconds, which is one day). Thus, when you make a change, resolvers on the Internet which have cached the old record may not update it until as long as a day has passed. It's best practice to shorten the TTL to as low as possible (usually 60 seconds) in advance of the actual change of IP address, so that ...

Turns out Server 2012 R2 Essentials is not compatible with AAD Connect. Essentials has a built in Azure directory sync however, which appears to do a similar job.

TL;DR E-mail servers will keep messages in their queue a few days if they can't be delivered. Normally during a migration, you'd have to change DNS records, but since you're staying with the same server (same IP) there's no need for that. You can simply shutdown the server, install the new one, and you're good to go. The only important thing is that you ...

You need to start from scratch on Office 365 and perform a cutover migration following the detailed step-by-step instructions here. You will need to obtain a valid public SSL certificate and ensure that autodiscover and outlook anywhere (RPC over https) are correctly set up and working. You can test this at http://exrca.com. If you're unable to make this ...

The hard evidence is lack of support coming in very soon. But migrating a complicated set of servers to a new platform is a tricky business - so the sooner you start it, the better. You might want to try it on one machine first, and build up on your experience. And since R2 has been out for some time, now is the time to do it.

If you add a second domain controller--which doesn't have to be beefy for two users--then yes, you can retain the existing AD accounts. Depending on the version of SBS08 you have, you might even have a copy of Windows server 2008 that came with it. Conversely... You can just create live accounts for yourusers@example.com and let them use those for ...

Domain rename worked just fine using Microsoft's rendom.exe utility (I'd say it was easy, perhaps because there was no exchange server involved). Service logons were changed for SQL Services and everything worked smoothly.

Got it. Apache 2.4 has additional security features.

This is fairly fundamental. Remove DC from domain using the normal procedure. DC becomes a member server in the domain. Remove member server from domain. Create new domain using the normal procedure. Job done. I'd personally be considerably happier if "re-image server" was included as a middle step to ensure that any info/cruft on the server didn't ...

disclaimer: I work for Linode To migrate your stuff, there're a few ways you can do it. You can make an image of your entire disk (this is EVERYTHING, including data files, DB, OS, etc). One popular way to do this is to boot into Rescue Mode (Finnix) and dump your disk to an IMG file used DD. You can then download the image over SSH - Block-level Backup ...

I think you are confused about what components are involved and what you have paid for. ESXi is the hypervisor that runs on the hardware. vSphere is the software used to manage ESXi hosts. When you use the free version, you get a single ESXi license that you can manage with vSphere. When you purchase the software you are able to run more that one instance ...

Probably you'll hit the DNS caching. First you'll need to wait for cache refresh of your visitors providers, then, if you decide to switch back, you'll need to wait again. Many Internet providers tend to override TTL and set it to 1 hour minimum. In my experience, visitors came to old IP many hours after the DNS change. I suggest to use some kind of ...

Please use a account that can access all files. How do you do the backup if even an admin can't look the file ? If you use a service account for the backup, use the robocopy under that account. If anything fail, please take ownership of the drive to be able to copy the data, but be aware you might have to redo from stratch the security on the new drive.

The nova help is a bit confusing, as it frequently uses the word "server" where "instance" is actually meant, and "host" where "compute node" is meant. OpenStack's terminology has changed over its history, and some of the terms used here are the historical old terms. So I experimented a bit to find out what these commands actually do. What I came up with ...

Not sure if you want to do this on a Zimbra server, but if it is a server you can use zmmailbox with a getRestUrl for almost all things that can be done in the web interface. Become the zimbra user zmmailbox -z -m mail@domain.com -t 0 getRestURL "//contacts?fmt=csv" This is a basic csv export, mainly compatible with Zimbra. You can make the exports more ...

Since Xen is an open source project, companies can create their own distributions. So basically OnApp XenServer and Citrix XenServer are based on the same underlying technology (Xen) and are generally compatible with other Xen distros. Because of that and as long as you have XenCenter access to the XenServer management IP, you should be able export the VMs ...

There are at least two possible things to do, depending on how your domain's DNS is set up. 1) If your domain's authorative name server is operated by your DNS registrar, then you need to log in to their control panel and change your domain's A records to point to your new server. 2) If your domain's authorative name server is on the same server than your ...

Couple issues I see. You mention two NICs, but it is not recommended to have a dual-homed domain controller--it should have just one IP address. You should have a firewall as your gateway and if it's really necessary to access your domain controller remotely, use port forwarding. You need to run domainprep before you can promote the 2012 R2 computer to a ...
