Comment 7 for bug 1495064

Now interestingly the 'south_migrationhistory' reports that migrations have been applied up to 0120 for 'maasserver' and up to '0014' for 'metadataserver'. Thus only 'metadataserver' 0015 is missing to be at the level needed for 1.7.6.

I have checked Diango-South and their IRC channel and already-registered "migrations" are not reapplied, so "upgrading" to 1.7.6 ought to be safe, at least as database structure goes, by carefully removing the 1.8.0 packages and installing the 1.7.6 ones, if that's possible. I'll do a test in a VM/LXC beforehand :-).
