CirrusF5 Upgrade having modules LTM,GTM,APM & ASM
Hi All, We have f5 VMs hosted in Azure and we want to upgrade these VMs. We are thinnking to spin a new VM with version 15.1.x and upload the backup of existing VMs which are running on 12.1.5....
Hi,
There are a lot of changes between v12.1 and v15.1, especially in the security modules.
Remember that when you plan for an upgrade to BIG-IP 15.x, F5 recommends that you must be running BIG-IP 13.x through 15.x to upgrade to BIG-IP 15.x.

A better approach could be upgrade from v12.1 to v13.1 and then try the platform-migrate option to go to v15.1.

My 2 cents.
