Possible to move repeater items from one field to another while maintaining the ID?

[bernhard]

Hi everyone!

Today I had to move some data stored in a repeater field to another field. I searched the forum and found an admin action by @adrian and came up with a new method in rockmigrations that can copy or move repeater items to new fields and/or new pages: https://github.com/baumrock/RockMigrations/blob/ad59425831c74e32034035afa9d2276f398cc2be/RockMigrations.module.php#L3536

Now I realised that there is a problem: The way this works is it creates new items and then removes the old items. But that also means that IDs change 😮 And I have referenced those repeater items from somewhere else.

Does anybody have an idea of how to do that?
