If there are particular elements you are concerned about because of the move, email them. Our Wiki emailed in concern because of just how frequently used Wiki Activity is on our site. We were fine to move over, in theory, but were very concerned about what would happen to our site activity with 0 replacement for WA that is as easy to engage with for younger and newer users.

They didn't promise to not put us on UCP or anything, but clearly our concerns about moving over when there is no replacement have been heard, as we have yet to be asked to move over and now they are pausing UCP transfers due to concerns similar to what we shared.

Wikia/FANDOM are reasonable. If you don't want to move over just because they can't listen; the software has to change. But if there is genuine reason you have concern due to how your specific Wikis operate, let them know and see if they can provide insight.
