Good day folks,

I'm experiencing the error message in the subject line and after doing some forum research I found this thread which is pretty much the exact same issue I'm having.  

I've looked up the instructions referenced in that thread and have them at hand. However i did have a question I wanted to run by the community first just in case it might be feasible.

I originally got this error on my new test system and had been somewhat focused there until I thought i would go and check the existing production system and see if it actually exists there as well. I found out that it does but I don't get the error when I open the Purchase Order section like I do in the test system. 

After searching, I found the POIVData files and took a look, there are two that are in the "in progress" state, however, there are two identical folders that reflect that they have been successfully upgraded. (Refer to the image to see what I'm talking about.) 

My question here is, would I be safe in just deleting those two "in progress" folders, performing the data migration again and see if that works? It's just a thought, I guess I'm just being lazy.
