It was not bad when I migrated all of my business returns a few years ago.  The Drake program highlights the items that need to be checked/verified so it was just a matter of taking care of that.  I have done about 10 personal returns this year because the clients were in a hurry and it worked fine, but these were simple returns   I am going to do the mass migration during the summer.  I am actually going to migrate some of my more involved returns from 2024 to 2025 and redo the 2025 on Drake to make sure I get all the little nuances and input kinks worked out during the summer months.
