Cisco 6807 VSS ISSU Upgrade

The Request: I have a client with multiple 6807 VSS pairs that required an IOS upgrade. All of the pairs have a single SUP2-T in each chassis and were in the 15 code train. Although the ISSU process is very straight forward I wanted to put this quick process up as I had to search through multiple documents to gather all the pieces I needed to knock it out.

Cisco Unified Communications Manager & Unity Connection SFTP Emergency Backup to Mac OS X over the Internet

The Request: I was engaged by a long time client who was having an issue with their local SFTP1 server. After some upgrades to their server infrastructure they noticed their phone/voicemail system had not been backed up in MONTHS! They asked if there was a way for me to perform an “emergency” backup to my system if they gave the voice VLAN access to the Internet temporarily while they fixed their SFTP issues....
