[horde] 'modseq'-values duplicated in 'horde_histories'

[Piper Andreas]

Hello,

on my Horde-Setup (horde-5.2.1 with imp-6.2.2, turba-4.2.2,
kronolith-4.2.2, mnemo-4.2.1, nag-4.2.1, ingo-3.2.1) the count of
'horde_histories_modseq' was somehow (re-)set to a very low value,
followed by the creation of entries in 'horde_histories' with duplicated
'modseq'-values. In consequence, ActiveSync is no longer working correctly.

For correcting this, I thought of recreating the 'modseq'-values in
'horde_histories' by running

horde-db-migrate Horde_History 2 followed by
horde_db-migrate Horde_History

which should remove all modseq-values and recreate them together with a
correct setting of 'horde_histories_modseq'.

Would this setup work as expected?

Or will this mix up my whole data (e.g. due to the use of the
'modseq'-value as fixed reference to some data)?

Thanks for any hints,
Andreas
