Migrating to other DataCentre and IPrange

[bazzi]

Hi There,

Sorry for the n00b question but I want to check my steps to migrate to a other datacenter AND iprange with my servers.

These are my steps:
OLD DC:
1. ``perl -pi.bak -e "s/14400/900/g" *.db``
2. Wait 48 hours
3. Change everything in the server so eth0 will bootup on new network
4. Run the migrate tool in WHM
5. Finish it.
6. Sync dns servers.
7. Shutdown servers

8. Transfer to new DataCentre

NEW DC:
9. Boot up and check if eveything is working.
10. ``perl -pi.bak -e "s/900/14400/g" *.db``

The downtime will be approx 15 min for the dns change and 30 for the actual transfer. So let we say 1 hour in total...

Is that right? Or am I something missing?

You have to change the serial number under each dns also.

[bazzi]

Thanks, I almost forgot....

[bin_asc]

There is no actual downtime if you use clustered DNS.

[verdon]

bin_asc is correct..

I recently did a move, more or less following the guide in this thread, and had no downtime at all.

Yes it is clustered, but the dc's are aprox 30 min drive from apart.

[bin_asc]

So you are moving your servers ( physically ) ?

[bazzi]

Yes we are moving our servers physically.

[bin_asc]

You should have said that in the first place )

[bazzi]

Yes you are totaly right. It was to obvios to me, so I forgot to mention... Sorry, but again it is a physical move!

[bin_asc]

Well everything that you pointed out looks ok.

[UBERHOST]

Yes it is clustered, but the dc's are aprox 30 min drive from apart.

We recommend long extension cords.

In all seriousness, did you finish migrating? Did all go well?

[bazzi]

We are moving this saterday, so I will reply if it went OK.

[bazzi]

everything went well, except one minour incedent:
We forgot to install test licenses, and the store returned a 403...
So that were some frustrating minuts

Thanks eveyone for the comments!

I am considering a similar move. At step 4 above, is it the "IP migration tool" that you are referring to? If so, did that work successfully?

Did you use zsu to update the serials?
