GTM 10 to 11 upgrade experiences

Excellent information Bhanu. I was able to talk to an F5 engineer who has been through this process. He mentioned the exact same renaming of sync groups that you employed.

The engineer also mentioned these other tidbits.

1) Re-activate the existing 10.x license. Reason: If your currently running 10.x license was activated before the release of the 11.x software version that you are installing, the 11.x software ( particularly bind/zonerunner if memory serves ) will not work properly and will not bring your entries over.

2) Disable the GTM synchronization as Bhanu mentioned. This will prevent your different versions of GTM from trying to sync with each other and causing potential problems.

3) Check all zone files for non-standard entries and fix errors before running the install. named-checkconf -t /var/named -z -j /config/named.conf

4) Run the install of the software into the slot. Apply the relevant hot fixes.

5) Reboot into the new OS to test the version. Run some dns queries at listeners running on the upgraded GTM.

Don't forget to make a full UCS backup and keep it off-system before you start this. You can always reboot into another slot, but just in case it never hurts.

We'll be giving this a try in the very near future.

Much thanks to Chad of F5 for spending a lot of time going over this with me. The conversation was much more useful than anything that could have gone into a ticket.
