There is a certain amount of manual work involved in doing this. First of all, switch on UTM in the audio preferences, then you will need to go into the environment audio layer and replace each pair of l + r channel strips with a corresponding stereo one. This may also involve tidying up some plugins.
Thanks for your reply Mark.
This is what we were afraid of etc, as we have a 100 or so tracks, 32 stereo bus's
with plugins, plus a fair few stereo audio tracks and when you switch it to universal
track mode, you would have to save copy paste every stereo bus and channel setting as the plugins are not there in UTM. So if you or anyone else has a time saving idea for this is would be great.
