I'm beginning a project where I will be migrating some hardware appliances and VEs to a new pair of vCMP hardware appliances. If I were going like for like it would be simple because I could just make the vCMP guest an HA to the current device and push the config. However, there are several changes that make this more challenging and I am trying to determine the easiest but safest path.
First, I'll be collapsing two or three environments into one set of vCMP guests. We have several instances of a prod environment that I want to put into one single prod environment (for example) so that it cuts down on the number of LTMs we need to manage. I am also going to put the VIPs into a different IP subnet so the VIP will change, I will be putting these into different partitions based on the business groups that will be using them.
I was going to manually configure these in the new system but I am wondering if editing a BIGIP.CONF would be easier or if there is something I am not considering that might be more efficient. I'm looking at roughly 400 VIPs.
We only use the LTM module and there are a handful of iApps that I might need to manually configure.
Thanks in advance.
Obviously without a deeper conversation this isn't a full endorsement of direction, but some thoughts:
