[cisco-voip] 8.6 Upgrades L2 Upgrade vs Refresh Upgrade

[Adam Frankel (afrankel)]

You cannot DRF backup and restore to a different version.  Normal L2 
upgrades make the use of "to side" (new version) binaries while still 
running in the "from side" (old version).   In previous versions this 
was not an issue as binaries from different rhel versions could be run 
across versions.   Rhel5 binaries cannot be run in Rhel4, creating the 
need for the RU upgrade.

HTH,

Adam
