Migration from 8.x-3.10 to 5.5.0-rc1 break several views

I'm now able to edit the view - what is great. But the view still shows

Is this fully fixable with an update hook?`

I guess it is caused by the card field settings. I have seen all fields title / content / image have been lost.

If you are able to edit the view and save new options, you shouldn’t see that message the next time you load the view edit screen. If you do, be sure to clear the cache.

I’m not sure what would need to be changed exactly in an update hook. The update hooks from this fix include what I found to map over. If you think there are more that need to be mapped for an update hook let me know. At least this gets you to a state where you can edit and make the changes that work for your requirements.

I think it would be perfect to migrate all previous settings. A clean upgrade should map all previous settings to the new and set good defaults to what is missing.

Manually fixing many views is really a lot of work and if this can be a smooth upgrade I‘ more than happy like many others who are also affected.

In a perfect world, that would be possible. However, there are many differences between the versions that make mapping difficult. Thumbnails to cards is not a 1:1. In fact, there are a lot of options not available. I'm trying to make it as smooth as possible, but there will be differences that I cannot account for. This is a major version difference both with Bootstrap and with this module. Some non-backwards compatible breaks are expected.

There is also the issue of some people who will be jumping from 3.x to 5.x and some from 4.x to 5.x.

I've done the mapping between versions and highlighted where there missing options between versions:
