Classic Custom Fields Vs New Custom Fields

I had issues with Batch operations and so went back to the Classic fields and everything seems to be working great. I’m reluctant to go back to the New custom fields. My question is that when the bugs are worked out of the New custom fields, will there be an easy way to migrate the fields w/ data? Also, I don’t want the risk of one day the program is suddenly broken. I plan to keep updated Excel files as an additional backup anyway, but just curious. Thanks

Yeah. The new ones are also not fully available in Custom reports.

I know the thinking is they do work in advanced queries but in many cases a custom report is more useful.

Be nice to see the functionality completed.

Would also be nice to have option to limit a given multi value field to allow only one value to be selected (still need to use the old ones when that is needed).
