CM to CM Business Edition 6000 migration

We're working with two medical centers with a high-speed circuit between them (they use a shared EMR application). Site A is already running Cisco voice (Communications Manager 6.x, Unity Connection and Contact Center), while Site B will still on a PBX. The goal is to unify the two centers onto a single Business Edition 6000 solution on redundant Unified Computing System servers (one at each site). Everyone will be on Workspace Licensing (CUWL) when said and done, so the new users are be purchased as CUWL, and the existing users at Site A will be upgraded. I see two strategies to get this done:

  1. Deploy the new CM Business Edition as a new installation for Site B, then somehow migrate/transfer the users on the Site A system over to it., or
  2. Migrate the existing Site A deployment to the new Business Edition on UCS, then add Site B.

The second option seems like the right approach, but I’d like some input/advice on which approach would likely be less painful.

Also:

  • Is there a migration path at all to get a system converted from CM -> CM Business Edition 6000, or will this require what amounts to a full rebuild on the UCS server, export/import users, etc?
  • Regarding CUWL, the existing users at Site A are DLU-based, while the new system will be CUWL. When migrating or importing users over, will their conversion to CUWL be automatic?
  • Although they’ll be sharing a single system, each medical center wishes to retain administrative control over their own users. So, they’d have a unified dial-plan an 4-digit dialing across both centers, but Site A’s tech staff would have exclusive control of managing their own users in CM, Unity Connection, etc., the same for Site B.

Any help/feedback would be appreciated, and thank you!

Re: CM to CM Business Edition 6000 migration

What would you recommend as the means of transferring all of the users/devices/configurations from the existing CM to the new C200M2 once it's up and running?  DMA clearly won't work - would you use BAT for export/import, or something else?

If the versions are the same (i.e. you upgrade the existing install to 8.0(2) or later first to get VMware support) you can use the DRS backup and just restore it onto the VM. This only works if they have the same OS-level configuration (e.g. hostname, security passphrase, IP address, etc) and the exact same version. If you can't get the versions to match you could use BAT with the export/import. This will be somewhat tedious though. For 400 users on two sites it may be easier to just build it from scratch IMO.

There's no way to have roles with different security assignments, or there's no way to even group users into different categories?

You can restrict read/write access only per-page. So you could prevent a group of users from accessing the Translation Pattern page as an example. You cannot restrict the search results however. If they have write access to that page, they can modify any record in the database that would appear on that page.

CM to CM Business Edition 6000 migration

Is there a migration path at all to get a system converted from CM -> CM Business Edition 6000, or will this require what amounts to a full rebuild on the UCS server, export/import users, etc?

There is no explicit migration path; however, a BE6k is just a UCS-C200 server with ESXi and a smaller scale VM of normal CUCM and CUC. This is a noteable difference from the BE5k which had an all-in-one software image. Since this is the normal software so you could just do a backup/restore if the existing install is on the same version.

Regarding CUWL, the existing users at Site A are DLU-based, while the new system will be CUWL. When migrating or importing users over, will their conversion to CUWL be automatic?

Uplifting from DLU to CUWL has a cost. The order will provide you new license files.

Although they’ll be sharing a single system, each medical center wishes to retain administrative control over their own users. So, they’d have a unified dial-plan an 4-digit dialing across both centers, but Site A’s tech staff would have exclusive control of managing their own users in CM, Unity Connection, etc., the same for Site B.

That's not going to happen if you have a single CUCM and CUC cluster. The only way to do this would be separate clusters with an inter-cluster trunk and CUC digital networking.

Also pay close attention to the significant sizing limitations (Table 1) imposed by the BE6k and UCS C200 platform. This applies no matter how many cluster nodes you add; once you build it on C200 hardware the cluster is hamstrung by that platform limit. Additional documentation for sizing is on the docwiki or available through your Cisco partner.

Thanks for the reply, Jonathan - a couple quick clarification follows, if I may:

Is  there a migration path at all to get a system converted from CM ->  CM Business Edition 6000, or will this require what amounts to a full  rebuild on the UCS server, export/import users, etc?

There  is no explicit migration path; however, a BE6k is just a UCS-C200  server with ESXi and a smaller scale VM of normal CUCM and CUC. This is a  noteable difference from the BE5k which had an all-in-one software  image. Since this is the normal software so you could just do a  backup/restore if the existing install is on the same version.

There's no way to have roles with different security assignments, or there's no way to even group users into different categories?  It MIGHT be acceptable if an administrator could at least be able to go to his/her site within CM administration, then drill down to see only those users.

Also pay close attention to the significant sizing limitations (Table 1) imposed by the BE6k and UCS C200 platform. This applies no matter how  many cluster nodes you add; once you build it on C200 hardware the  cluster is hamstrung by that platform limit.

Got it - they'll have about 400 users total, so we're good. 

Thanks again!

Thanks for your help!  DRS should do the trick...
