CCM030X Databases

I have a customer who is splitting up a cluster, meaning they have 6 sites now and need to split the cluster into three seoarate clusters.

I am trying to figure out the best way to migrate the data across and am wondering if anyone has a recommendaation. I don't have a problem working at the SQL level except for the fact of all of the replication that needs to be undone, then redone again but that is not such a big deal, however when I ported from on server that has a 3.1.2c database named CCM0302 to another server built initially to 3.1.2c with a database of CCM0300, all of my services hang.

Desperately need to get this going today and any ideas would be useful.

Re: CCM030X Databases

I would recommend building each of the new servers and then using bat to import the data. I don't think you are going to have good results just migrating the ccm030x database.

Thank you,

Re: CCM030X Databases

I could use BAT for phones but there are many, many gateways and parameter configs and all of that other good stuff out there that has all been tweaked.

I was able to export from one CCM to the other into a new database but after setting up the replication and publishing, CCM thinks it's a subscriber. Very strange as I have done this before migrating to a new server platform. The only difference there was that the server name, etc. were all identical.

Manual entry and BAT are what I did, I am just wondering if anyone has an idea how to do this more easily. I think BAT needs a new tool called "Generate BAT files" which will dum your existing config out to BAT files.

Wouldn't that be nice?

Re: CCM030X Databases

It's been said on here before and I've not used this but here goes.

You can promote a subscriber to a publisher by running the upgrade to the current CM version (3.1.3SPD - 3.1.3SPD for example) and at the screen which says I am upgrading the subscriber, change it to publisher.) This should then allow you to break the cluster into 2 halves. I would reccommend taking the subscribers off the current network before trying this.

You then have all the info in a Publisher for you to use in the second cluster and all you need to do is delete the non-required subscribers from the clusters.

Like I say I've never tried this but it seems the easiest way to do it, and you can always remove a drive from the machine you try it on to roll back if it all goes breast plate skyward.

Re: CCM030X Databases

If this would work it would not be supported by Cisco TAC or the Business Unit that produces callmanager so I would recommend against this procedure.

There is not cisco supported way to promote a sub to a pub. Which is what you are wanting to do.

Thank you,
