Nice post to read. Helpful. I guess my biggest question is around support of the tool with various Una versions. Some of my research indicated that 13.x was the last supported version due to schema changes which did not play nice with the migration tool. To get me started, I am migrating with 13.1 right now - and it's generally working OK, with a few issues. (Conversations are being difficult right now). My plan was to do a two step - move to 13.1 and then to 14.x - but I'll keep working on it.

The other interesting thought from that thread - It seems to imply that migration to 14.x is possible directly, with the exception of the php version issue. In my case, I have the existing Dolphin site running on PHP 7.x, and the new Una running on 8.1 currently. I could go to later, but the migration script was throwing some deprecated warnings, so I settled on 8.1. If indeed it is possible to go direct to 8.4, I'd spend the time to find and fix the deprecated code in the migration tool, but would be curious if others could comment if it SHOULD work going direct to 14.x version of Una. If so, I'll take the time to try to get it in one step.
