Somewhere... yes, that's exactly the state of cyrus documentation.
On XFER the cyrus.squat file is ignored/dropped and rebuilt at the next run.
That's ok so far.
But the point is that 2.5 promised an upgrade path without IO havoc like
2.3->2.4 which needed an "on first access" reconstruct. But dropping all
DBs and rebuilding them is exact the same nightmare again.
cyrus.squat has a version number inside. Making it incompatible while
the same version is simply stupid and a bug.
