Puppet users - Nov 2013 - Migrating from Puppet open-source to Puppet Enterprise

We have perhaps 40 to 50 systems, give or take, that are mostly under 
Puppet management (not all).   After having spent some time doing my own 
thing with open-source, I''m looking into migrating to PE.

One question I have is relative to initial deployment -- if I decide to 
keep PuppetDB on the same server as Master, can I later migrate that role 
off onto another host?    I don''t believe we have enough traffic yet to
justify breaking this all down (yet) -- and this will greatly simplify 
things.

I also have the daunting task of re-writing all my individual manifests 
into proper modules :-)

Thanks!

You definitely *can* move PuppetDB to another host, but I think you''d
either be mostly on your own doing it, or need to reach out to support.
AFAIK it''s not supported by the installer, and I don''t
remember seeing
documentation on it.

The hardest part would probably be moving PuppetDB''s database, but
aside
from that, it''s really just a matter of telling the PE installer to put
PuppetDB on the new host, and then changing some configuration files to
point to the new host.

If you happen to be building this out on VMs, I''d recommend splitting
them from the start, and just adding resources as needed. But if you''re
looking to purchase PE, I imagine that puppet labs support would be able
to give you some advice on this.

Puppet support engineer here.

It would take some configuration tweaks to do the migration, but it should 
be doable.

Once you''re set up with a support plan, we can definitely assist you
with
that :)

Thanks, Jason.  I may toss the DB into a separate VM (the Master is on a 
real-iron system) just to be safe.   As for the other roles, I think most 
of them can live happily on the Master with our smaller infrastructure.

Thanks, Jason.

On a related note, we have maybe 50 +/- hosts -- and though we do use 
VMWare, I am not sure we really need separate hosts for all of the Roles. 
For example, the "master" will be on real-iron, and the PuppetDB will
be
(for now) virtual. But another role for Console seems like overkill.

I don''t expect our environment to get substantially large, but it could
happen. It seems that once you make a decision on this during the 
installation, it''s going to be very difficult/tedious to try and change
it
later on.
