Moving vCMP guests to newer blade - upgrade resources at same time?

Hi all -

 

I'm working on replacing my old B2100 blades with new B2150 blades. I'm running vCMP with the LTM guests at v12.1.2. Some of these guests have been challenged resource-wise and, since the 2150s have twice the CPU/RAM as the 2100s, I want to add resources to them.

 

I'm planning on using the method here: https://support.f5.com/csp/article/K63705154 (Migrating a BIG-IP configuration to new Viprion blades using ConfigSync) and have a spare chassis where I have built the target host cluster.

 

So the big question is, can I go from, say, two CPUs in an existing guest to four CPUs in the target guest? I don't see anything referring to the CPU/RAM resources in the document, but may have missed something in my first reading. Has anyone done this? I will need to add resources to them eventually and thought this might be a good opportunity to kill two birds with one stone.

 

The first upgrade will be to the standby systems - with the active systems held as-is in reserve in case any issues pop up in production with the new configuration.

 

I appreciate any feedback.
