Cyrus upgrade from 2.1.18 to 2.2.13 moved email messages

[Alain Spineux]

You would have won some time if you had read one of my previous post
in another thread
about pitfall you can meet when migrating. The thread title is
"Migration 32 to 64 bit".
It could still help you to understand what you did :-)

Be aware that we are not all debian user, and dont know the script and
tips provided by
debian to help in migration. Anyway specify the source of your
information and actions
is a gooud practice.

This is the directory hashing problem Sebastian is speaking about.
Just restore fulldirhash and hashimapspool to the original value
and it should work, but then you will have a lot of useless directories
created at mailbox restoration with the bad hashing schema.
But it should work.

Or maybe try rehash, but I never used it.

Good luck
