Hi, I have an Umbraco 11 site that uses Nested Content (it was originally a v8 site) and I want to update it to use the BlockList editor. The problem I have is that Nested Content is used quite extensively throughout the site for live content. I was thinking of changing my editors to BlockList, then using a SendingContentNotification handler to convert the property value in the CMS. That would be fine for content editors, and the actual value (which is still Nested Content at this point) would be updated to BlockList on the next save. But what about on the front-end, I'd have to handle both scenarios - one where the content is a BlockList, and one where the content is still in the old Nested Content format? It just doesn't feel right. Has anyone gone through this already?

I would probably use Usync migrations to move from nested content to blocklist. My process would be run the migrations on my local machine. Then fix the frontend to work with blocklist. Then copy the live database and run the migrations on that, and test it. Then i would deploy my frontend changes and use the migrated database as the new production database
