I currently have 3 hosts running 3.01 and a 2.0.1 management server with SQL 2000
I plan to upgrade the existing hosts to 3.5 and create a new management server running version 2.5. Here are my plans. Please advise if I've got any mistakes in here.
1) Backup database
2) Upgrade management server to 2.5 (this will toast existing licenses but everything should still run for 14 days)
3) Backup database again
4) Build new management server and install SQL
5) Import database
6) install version 2.5 using existing database
7) upgrade hosts to 3.5
8) install and apply new licenses
There's also a SAN and fiber switch expansion, as well as 3 new hosts for fresh installs of version 3.5.
Are there any gotcha's in this process? Obviously the existing hosts will be in maintenance mode for the upgrade. Will DRS still work between a version 3.01 and 3.5 hosts?
