Financial considerations have forced me to undertake something no
admin ever wants to do ... a server migration. But the money I'm
saving on a monthly basis is going to have to make it worth it
(especially since I'm getting a better machine).
I'd like the wizards here to please take a look at my plan and point
out where I've screwed it up or what I've forgotten.
I'm coming FROM:
- netmail 1.05/LWQ + lukasfeiler.com-bigqmail-20070526
- djbdns
I'm going TO:
- netqmail 1.06/LWQ + lukasfeiler.com-bigqmail-20070526
- djbdns
So the plan is ...
1) Create necessary user accounts on new box
2) Configure new box for rcpthosts/locals/virtualdomains to mirror old box
3) Create necessary delivery instructions on new box (.qmail-*, etc)
4) Modify djbdns/root/data to reflect new server as primary MX and old
server as backup MX
5) Remove domains from locals/virtualdomains on old box, but leave in rcpthosts
6) Restart qmail on old box, and immediately after ...
7) Make djbdns/root/data to make new MX settings live
8) Wait out a reasonable propogation delay
9) Modify djbdns to remove backup MX
10) Decommission old server
Feedback muchly appreciated. Thanks!
