Upgrading from SLES 10 SP2 to SLES 11 SP2

Question

I am running Suse Linux Enterprise Server 10 SP2 and I need to upgrade to SLES 11 SP2.

Can I just write a script which will install all the RPM's present in SLES 11 SP2 on my SLES 10 SP2 system. Would this be a good approach for upgrading to SLES 11 SP2. I am thinking of this approach because there is no direct upgrade path from SLES 10 SP2 -to- SLES 11 SP2.

Also, why do vendors don't support direct upgrade path?. My understanding is that everything that gets installed on SLES is through an RPM.

Answer 1

Distribution upgrades on SUSE systems are done using either command-line zypper or yast2's upgrade frontend. You may need to manually adjust URLs; if so, they are in /etc/zypp/repos.d.

The direct upgrade path is implemented, but the support hotline may not want to talk to you about it. Well, RHEL people won't either. That is part of their business plan. If you do not like that, consider moving to e.g. openSUSE.
