Hey,
Because we have legacy devices in the field which have a version 4 microserver and can only communicate using XMPP, our TW server still has to support XMPP. For TW version 5 and higher, the AlwaysOnSubsystem extension was needed for that. Is this extension (already) available on Thingworx 7? This page only lists extensions up to TW 6.5: http://support.ptc.com/appserver/wcms/standards/freefull_cs.jsp?&im_dbkey=162654&icg_dbkey=893
Regards,
Stefan
