<div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">I suppose I wasn't clear. I would be setting up new servers for each piece and moving the mailboxes over from Kolab 2 to Kolab 3, not doing an in-place upgrade. What I am wondering is if I would be able to do that piece by piece due to resource constraints. As in setting up new Roundcube servers first and then switching to them and shutting the old ones down. Then setting up new frontends and switching to them, shutting down the old ones. Setting up new postfix servers, switching, then shutting down the old. Then setting up new backends, migrating the mailboxes and switching to them, and shutting down the old ones. </div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">Is that possible? If so, what would the preferable order be? Obviously, it would be best to do the entire environment at once, but I am constrained at the moment by resource availability. And yes, I need multiple servers for split services - I have tens of thousands of mailboxes to work with.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Feb 26, 2015 at 11:48 PM, Christian Tardif <span dir="ltr"><<a href="mailto:christian.tardif@servinfo.ca" target="_blank">christian.tardif@servinfo.ca</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>You won't be able to do some sort of migration from Kolab 2 to Kolab 3, as you'd do for Windows 7 to Windows 7SP1 (beurk....)</div>
<div> </div>
<div>The reason behind that is that Kolab 2 and Kolab 3 are complete different setups. Kolab 2 is installed on OpenPKG, while Kolab 3 is built on standar Linux distros. Another big difference is the LDAP database. Both environments are configured very differently.</div>
<div> </div>
<div>There was some partial documentation on Kolab 2 to Kolab 3 data migration, which was far from complete, and not suited for all situations.</div>
<div> </div>
<div>The best way to go is to install from scratch, create your users, and then migrate your emails with something like imapcopy or some tools like that. You'll probably save yourself a whole lot of trouble.</div>
