How to force file renaming after changing max_filename_length option

Help
1

I’m forced to change the max_filename_length option because some filenames are too long for a target backup filesystem.

How do I get the existing files in my library to be renamed following the new max_filename_length setting? I tried beet move but nothing was changed.

I figured it out. I had to import the problem albums again.

Probably too late but maybe for next time: Have you tried doing beet move <query finding problem albums>?
