[cisco-voip] Upgrade from 3.3.4 to 4.1.2 - 5000+ phones

[Lelio Fulgenzi]

We're in the same boat, however, we were told not to upgrade to 4.1.2 but to 4.1.3 b/c of the fact that they will be paying attention to bug fixes on 4.1.3. If the bug is found in both 4.1.2 and 4.1.3 then the bug will be fixed in 4.1.2 (likely low priority) however, if the bug is fixed in 4.1.3 they will not fix it in 4.1.2.

  I'm looking for an organization that has done a successful upgrade from 3.3.4 to 4.1.2 on a large scale. 

  We have 5000+ phones, pub, dedicated tftp and 4 subs in 2 campuses; also an IPCC box running 3.1 which we would be upgrading to 3.5 too. 

  The recommendation we received from Cisco was to upgrade to 4.0.2 sr2, awaiting to have larger deployments running stable on 4.1.2 before committing. 

  I'm interested in things like, 

  Did you run into any unforeseen issues? 

  Did failover work fine? 

  How long did it take to complete? 

  Did you experience any problems after the upgrade? Or has it been smooth sailing? 

  Your thoughts on this would be appreciated. 

  Thank you in advance. 

  Mayte.
