Continue use of old macro files

I understand the MG Pro with the new MIDI Remote has all commands that used to be in the previous metasystem_macros, metasystem_macros2, metasystem1, metasystem2, metasystem3 etc are all integrated in the Commands in the remote correct?

1. in that case if someone uses the legacy system in addition to MIDI Remote does that trigger the button action twice?

2. If the above is true and I have added my own macros to metasystem_macros is it advisable to remove all original commands and keep only mine? (or create a new xml file to avoid being overwritten).

3. Are we still using Metasystem - Cubase as the MIDI port for the legacy way?

BTW as part of computer management many of us don’t use the C: drive to store anything and moved documents, presets all to another drive but metaserver 6 for Windows is still fixated to reinstall the macros files on the C: drive
