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.

Hi,
If you have more cores on new blade, you can assign them during the migration.
- Migrate configurations on new blade
- Bring guest device to configure mode
- Assign more cores
- and then deploy the guest with assigned new cores
Follow same process with active chassis/blade and guest (Active).
