Sepasoft vs. Ignition for MES

We have a pretty stable home-grown MES system that we’ve been using for over 20 years.

Needless to say, it’s in need of an upgrade. Our process isn’t entirely unique, but the same part number can take hundreds of different routes on the way to becoming finished product.

The question here is whether we should use something like Sepasoft, or whether we should more-or-less port the existing MES into Ignition. It seems clear to me what would need done to port the old MES into Ignition, but I have no idea what a switch to Seapsoft would entail. In my mind, it has it’s own schema, and thus, everything that relies on current MES schema would need refactored?

Any opinions on whether the costs of Sepasoft would outweigh the benefits?

Thank you!
