I have a 3.5 environment (1vCenter, 2 ESXi) , am rolling out upgrade to 4.1. The plan was to:
backup vCenter 3.5 then shut it down,
light up separate vCenter 4.1, migrate database to it,
introduce new ESXi 4.1 server, move guests to it from one 3.5 ESXi server, decommission that 3.5 ESXi server,
introduce another new ESXi 4.1 server, move guests to it from second 3.5 ESXi server, decommission that 3.5 ESXi server,
Done.
today I installed 4.1 vCenter and an ESXi 4.1. vCenter is getting an error on one of the 3.5 hosts that it needs a license server. Oddly the second server doesn't say the same.
Do I need to install a license server for my temporary setup?
Is my migration plan reasonable?
thanks!
