samba - Aug 2014 - Upgrading Samba in a Multi DC environment

Hi all,

I currently have 5 DC's all running 4.1.5 and would like to upgrade them to
4.1.11.

Should I upgrade the FSMO DC first and then the others or perhaps the other
way around?

Can anyone see any pitfalls here?

Also, should I just:

1. stop samba
2. ./conffigure && make && make install
3. restart samba

?

I am also planning on switching to BIND_DLZ (currently running Samba
Internal DNS). Would it be wise to perform this change before upgrading or
vice versa?

Thanks,
Chris.

Forgot to reply all...

To minimize downtime you can configure && make, then stop samba, then
make
install, then start samba.  I don't think it should matter on the order you
do them, but I don't know for sure, can any one on the list confirm this?

There's no special order to follow.

The FSMO roles are just a few attributes inside the AD, that defines,
which DC(s) are responsible for the 5 different jobs (roles). They
doesn't matter when you upgrade.

No. There should be nothing special if your current version isn't an
early 4.0 or prior 4.0.11/4.1.1.

If you want, you can check for errors in your AD:
# samba-tool dbcheck --cross-ncs

Yes.

Doesn't matter. But usually I don't recommend to make two new steps at
once, because it could make identifying the reason for problems more
difficult ("caused the update your DNS problems or the new backend?").

A guide for the DNS backend switch you find here:
