Upgrading from a really old Samba 4?

[Michael Wood]

Hi

Summary:

I'm running a really old version of Samba 4 (77b9b97) with the DNS
records in a normal bind9 zone file.  No need for dyndns, since I
don't have machines joining/leaving the domain.

There seems to be a memory leak in that version.  Otherwise it works very well.

Questions:

If I were to upgrade from such an old version, is it necessary to run
upgradeprovision?  (I know that running upgradeprovision is not
recommended right now, in which case would I need to wait until
upgradeprovision is fixed?)

If I do need to run upgradeprovision, what order do I run it in wrt.
dbcheck and/or the DNS upgrade script?

Thanks.
