dovecot - Jun 2012 - Upgrading 1.2.17 -> 2.1.x

We're planning to upgrade our site from 1.2.17 to 2.1.x within the
next few months, but we must ensure our ability to revert to 1.2.17
if problems arise.

I don't expect our maildir storage would present a problem,
but am less certain about 2.1.x index/control files remaining
readable under 1.2.17.

Should I have any reason to worry?

1.2.17 can read v2.0 indexes without problems (it has some forwards
compatibility code). I don't think I added any incompatible changes to v2.1
either, at least nothing major..
