We have separate LTMs and GTMs. When we upgraded the GTMs, it went smoothly. When we upgraded the LTMs, the GTMs' pools lost half their data! The V11 conversion changed LTM Virtual Server names by adding "/Common/" to the front of the names. There were no longer any LTM Virtual Servers on the GTM with the old names, so the old names were removed from all GTM WideIP Pools.

 

Fortunately, we had kept copies of all the old configuration files, so could reconstitute the states of the pools (and VS-dependent stuff like dependencies) using 'tmsh' statements. But it was annoying. And F5 tells me there is no workaround.

 

It did occur to me later that I could have set "Virtual Server Discovery" to "Enable (No Delete)" before upgrading the LTMs, and then move the changes over. But that would probably not have worked, as F5 says there is no workaround.
