By keeping Windchill 9.1 M070 can I update the Arbortext Editor (from 6.0 to 6.1) and IsoDraw (from 7.2 to 7.3) and creo Illustrate (from 3.0 to 3.1)?
I'm moving this to the Windchill Community, since that appears to be your primary question, but please be sure to look over the compatibility charts available on the PTC site at:
Windchill 9.1 M070 does not support Windows 10.
Arbortext Editor 6.1 does not support Windchill 9.1
Arbortext Editor 6.1 F000 supports 10.0 M040
There are software matrices reference documents at the PTC website www.ptc.com/support that may be reviewed for application version support
Arbortext Editor 6.1 does not support Windows 10
Arbortext Editor 7.0 M020 is currently projected to provide support of Windows 10
