Switching from Glide Tables to Big Tables

If I have built my app using glide tables an switch to big tables do I need to reconnect all my user side fields to the Big Table or can I use linking for that?

What do you mean by “user side fields”? Do you mean computed columns? If so, it’s a yes, since it’s a completely new table.

You would also have to take into account its limitations.

I mean in the layout view, where I am connecting the UI to the table. Or is there an option to replace which tables it is connected and it automatically finds the correct columns on the Big Table if I use the same column names?

No, we don’t have anything like that at the moment. You would have to re-do all computed columns, and connect everything again on the front end.
