[cisco-voip] Thoughts on Major UCM/UCCX upgrade

[Lelio Fulgenzi]

two general comments: 

(1) there is supposed to be an N+1 compatibility feature with UCCX and UCM to make upgrades a little easier. problem is, i think if you wait too long, the +1 passes by quickly. 

(2) not having support is something i wouldn't even attempt. there are too many things that can go wrong. i understand that it's expensive, but really, how can you go forward without it? i know there's this list and the forums, but i don't think it's a replacement. 

not sure if there is incident based support from either Cisco or Resellers, but essential support gives you access to minor upgrades as well

Subject: [cisco-voip] Thoughts on Major UCM/UCCX upgrade 

Hi All, 
My company is considering doing a major upgrade from our existing UCCX 7.0.2 and UCM 7.1.5 to ucm/uccx 8.6. They are also considering discontinuing the support contract from our value added reseller, which would mean that the upgrade would be performed solely by our engineering staff. We've done a few minor upgrades on each platform without issue, but after reviewing the upgrade compatibility guide for UCCX, it seems this particular one will be very difficult. My assumption is based on the fact that we can't upgrade one platform or the other first, and verify stability for a time period before continuing on with upgrading the second platform, since neither one supports the other's previous version. 


To clarify> CUCM 8 does not support UCCX 7 
CUCM 7 does not support UCCX 8

My questions are: 




1. Has anybody tackled this yet? 




2. where there any problems, major or minor? 




3. what was the general path you took for upgrade? Did you do everything at once, or build a separate system on another piece of hardware(we are considering this as well) 




4 Any other thoughts? 




Thanks in advance for any input you might have on the matter
