[cisco-voip] Migration from CUCM/UCXN/UCCX 8.5 to 12.5

[Lelio Fulgenzi]

Jabber used to have a feature on iPhone where it would auto-dial a number when Jabber was brought to foreground and phone placed against ear.

We sent it to our voice activated dialer. Worked like a charm. Miss that feature.

So, PLAR all around? Pick up the phone, get an operator, and ask the operator to connect you to your party. That sounds great.

Replying off-list…

Yes, I took down our telephone system once by inserting a blank translation in the none partition.

What did I know? I was young and naïve. 😉

Of course, with CCM v2 or v3, anything was possible. 😉

I call blank translation patterns. 😉

Or turn it into the first cisco-voip community project, and we all jump in and help?  I call translation patterns!

Here’s a fun one. We have taken over support of these ancient servers hosted on Esxi 4.1 on UCS-C200-M2s!

Exact Versions are:
8.5 SU2 for CUCM/UCXN
8.5 FCS for UCCX

Each  is a pair of servers.

Have new M5s and flex licensing… need to get to 12.5..  8.5 docs are dead for CUCM/UCXN and 8 and 9 docs are dead for UCCX. ISOs I may need are not available publicly.

Also fun wrinkle the new host are across the WAN and for many logistical reasons are staying there. The migration to the new hosts will have to be via DRS or maybe PCD somehow? Not sure if the bandwidth available to get data across will be fast enough to finish in the allotted time period. My plan was a change freeze window and copy/restore the backups and then activate the new servers and move the subnet to the new location.

As best I can tell I need to get UCCX to SU4 of 8.5.1 then I can go to 10.6 SU3 and then to 12x (with the fun of two CAD upgrades and then a migration to Finesse!)

For CUCM/UCXN I need to go to 8.6 anything and then I can go to 11.5 and then to 12x

I think my plan is to do the upgrades to the interim versions on the old hosts then migrate to the new and then finish the upgrades. The old hosts will need ESXi upgrades to an interim version.

Anyone have thoughts on what they would do here? This is partially depending on TAC being able to provide me the ISOs I will need, but I presume there is an archive.

In theory some sort of PCD migration is also an option, but I’ve never done one and not sure how it could handle the subnet situation that will have to exist.

Welcome to my fun life!
