I’m trying to plan our M2 migration. This will be a months long effort and I am trying to determine the best order in which to proceed. It seems logical that migrating our current data using the data migration tool should be one of the final steps, however a large amount of work depends on this data being in place, such as testing extensions and developing the front end. I suppose we could migrate the data at the beginning, but I am somewhat afraid that during the long testing process some of the data may be changed.
Does anyone have any advice, or know of a best practices guide for a M1 to M2 migration?
