node name re-written: Upgrade from v10 - V11

So I have ran into the same problem and was wondering if anyone figured out a reliable fix. I have about 100 nodes & 62 pools. We run multiple services per node on different ports, but they are mostly on one /24.

 

 

My biggest problem is that now that the name has moved, you cannot add a node from the node list by name; only IP address. We have a team of engineers that work on the different applications, and we have already had 1 production incident where the wrong node was added to a live pool because the engineer was off by 1 number (.145 instead of .146).

 

 

I tried manually updating the bigip.conf file in our test environment twice, and each time a different product had issues. I'm reluctant to do such a major change across the entire F5. Has anyone written a script or anything to help? I opened a ticket with support, and they basically said I need to delete the nodes & re-add them (not realistic at all).

 

 

Anyone?
