There is a Library Master utility to update those paths.  It is awkward and slow, but it's all you can do with Sage provided tools.

(If your Sage Partner is a member of 90-Minds, have them ask there for a private utility that works much better).

I have both of those and what is going on the files name changed and added the folder name in front of the original file name so the Sage Link is not recognizing the PDF files.

I need to rename the file names to take out the folder name at the beginning of the file name.

AS you can see what has happened.  The folder name was placed at the beginning of the filename

Is there a way to import into a system file?

I don't know of any easy way to update the file names.

What utility did that?

I did the 90 minds utility first and there were a lot of unlinked Files after, so the I ran the Sage utility, so I am not sure which one did that.

Did you take backup copies of the M4T's?

Yes, but they have transactions since the upgrade so I would prefer not loosing that information?

Maybe reach out to DSD to confirm if LMAD would work for those files.
