Reset TFTP after and reset the phones again if you want to be extra safe. Every time I've done this, it worked in the single step of just switching the parameter and having it reset all the phones. Definitely can't be too safe with these though. I'd also say pre-prepare by enabling web

Interesting. We’ll have to see how 11.5 plays into the process. We plan on testing things on a development cluster to ensure the process works. Last thing we need is to have staff reset their own phones. Yuck. --- Lelio Fulgenzi, B.A. | Senior Analyst Computing and Communications Services |

Re: [cisco-voip] Prepare Cluster for Rollback to pre 8.0 Parameter - still valid for moving to different hardware?

Thanks Anthony. By setting the parameter, the phones reset automatically. Are you saying that I have to reset the TFTP server before setting the parameter? Our previous scenario, which was pretty much just an upgrade using new hardware required this. We couldn’t get it to work without it.

Re: [cisco-voip] Prepare Cluster for Rollback to pre 8.0 Parameter - still valid for moving to different hardware?

That's what I would do. Sometimes new versions have issues with restored certs so may be worth doing the rollback method and not completely relying on DRS. If you have 2 clusters with different IPs and both online at the same time, definitely a better idea to use the Bulk Certificate

Re: [cisco-voip] Prepare Cluster for Rollback to pre 8.0 Parameter - still valid for moving to different hardware?

Your first step is incorrect. You need to restart TFTP and TVS first, then reset phones. Now, the scenario you described, you wouldn't even need this, would you? Because your servers and more importantly, certificates, are staying the same, you're just upgrading the application. Unless of

In the past, we used this parameter to prepare phones to be homed to a different set of hardware. For example: * Set parameter to true, reset phones. * In an offline network, restore from DRS and upgrade servers * During a maintenance window, turn off version A servers and turn on
