Renumbering networks and F5 Load Balancers

It looked like the mass edit didn't work because HA kicked in and synced the config by itself even I swear it should be doing it.

 

 

We had changed the on disk files, rebooted the active LB and when it came up, it grabed the config from the standby and all changes were lost.

 

 

But we have 4 different environments on the production systems (Production, 3x Demo) and Management wants them to be changed seperatly. So I am looking at having to do:

 

 

Remove Node A from all pools

 

Delete Node A with old IP

 

Add Node A with new IP

 

Add Node A to approriate pools

 

Repeat for all other nodes

 

Change IP for all Virtual servers.

 

 

In total about 783 IP entries to change.
