We have a custom field that was originally created as plain text instead of rich HTML text. Since we cannot change the field type directly, I am creating a new rich HTML text field with a similar name.
It's important that the existing plain text field remains visible in prior tickets for reference, but it not be visible or fillable in new tickets.
I'm unsure whether it would be better to move the existing text data to the new field or if this is even possible. Could you please advise on the best approach?
