Hi I have an existing and new server that are part of a windows domain. I want to redirect network traffic to the new server and keep the existing one online short-term then offline it after a few weeks. There will be no IP changes of hosts, and I cannot re-name my existing Server001 to reboot with a new name like Server001-OLD... but I am hoping I can rename it at dns level??
This is for a MS SQL DB server and contains Shared Folders accessed via UNC path. An ETL Server will access shared folders and the SQL Server DB based on host name "Server001" My goal is to allow connections to route to the new server(serverP1) using the existing server name (Server001) without changes and any 3rd Party software also continues to run (e.g. backup software)
For example: An older server, called Server001 (10.10.10.1) and a new one called ServerP1 (10.10.15.1)
Will this work successfully:
Can I request my DNS guys to update DNS:
Server001 to Server001-old (retaining current IP 10.10.10.1) hoping this will stop traffic going to old server
Create a new DNS entry CNAME /alias named Server001 referencing ServerP1 (10.10.15.1)
Thanks for any help!
