We have not made a decision on MFiles migration. We are focusing first on making ours. It's a long dev cycle.
At some point we will analyze the situation more clearly. Given MFiles is very expensive and tends to not care about single users, and since we have had no formal arrangement with them for many years, it is my expectation that what we will find is almost all such users have stopped using it. Of course, not all have.
My guess is that interfacing with (any number of different versions of) MFiles going back many years would be required, which in itself is a huge research project. Development would likely be quite non trivial, after all we are messing with data at that point. So it will depend on if the people benefiting from this work number in the 20s or the thousands, considering putting developers on this negatively affects every other customer who will miss out on feature development.
My guess is that it is unlikely we will do that. But again I have been wrong before and will be wrong again. We need to run a survey and figure out what we are dealing with.
I know that's not the answer you wanted, but it's at least the truth. There is also the fundamental problem that neither our PDM, nor any other PDM, is MFiles. I say that just to reiterate that MFiles is highly customizable, and they have concepts we do not have, or do things in different ways, etc. Even if we decide to have a migration tool from MFiles, it's certain a lot of "stuff" related to MFiles, like customizations, will not transfer. So there is a lot to consider, and we will do it more thoroughly when we get closer. There is no possibility we will do it prior to the launch of Alibre PDM, as we just don't have the time.
That said, we do not plan on ripping out MFiles functionality, though it is also true that we do not actively develop against their API, except in cases where surgical precision is possible. However it hasn't changed in many years and I don't expect they will kill all past integrations by screwing with it on their end any time soon.
