IDvX tags out of sync

Has anyone created an "action" to resync field content between tag versions? I believe that I have a number of files with out-of-sync content of one or more ID3v1 and ID3v2 fields.

Should I simply delete the ID3v1 fields? or will this mess things up?

Is there a "best practice" for cleaning this up?

Thanks!

You can sync by saving the tags again.
Note: Mp3tag displays only one tag type
For example, if you have the following options:
Read: ID3v1 and ID3v2
Write: ID3v1 and ID3v2

Now you have a file with both tag types, then what you see is the ID3v2 tag. If you save the tags now [Ctrl+S] the ID3v1 tag will get the same values as the ID3v2

Thanks, dano.

Is there a way to identify the files with out-of-sync tags?
