You must dump one repository at a time. You can probably write a
small script to automate it if you have that many.

I don't know what a "swing migration" is but it certainly appears
that, through whatever means, you have a different version of BDB on
the new machine. You can perform some steps to upgrade the repository
to the new BDB version; the FAQ has some instructions:

But I personally recommend the dump-and-load strategy and migration
to FSFS. Many people have reported problems with BDB repositories,
and only a few have reported problems with FSFS. Though many people
also have success with BDB, I personally choose not to take the chance.
