Sorry also, I missed a step. Once you've installed the new manager and taken a backup of all of your licence codes, backup your configuration too. To downgrade first format the SD Card but only do this in R7 MANAGER, not Windows because the SD card is watermarked to Avaya.
Steps to format the SD card in Manager (Again DO NOT use Windows to format the card):
Insert the SD card thats in your Avaya IP Office into your computer
File menu > Advanced > Format IP Office SD Card > and select the appropriate Law for your region (A-Law or U-Law).
The card will quickly format.
Steps to recreate the SD Card in Manager:
File menu > Advanced > Recreate IP Office SD Card > and select the appropriate Law for your region (A-Law or U-Law)
This will take some time to complete unless you have the experience to edit files to remove languages you don't need.
Once the SD card is recreated, reboot the IPO if it hasn't already, upload your config or start a new one depending on what you want to do, then reinstall all of your licence codes one by one. After this, reboot the IPO again and you should be good to go.
