Can Old TDM Expansion Chassis be used with Accel Cards?

[i hear dead people]

I have an older expansion chassis -- branded with the Digi logo -- forgot exactly which one -- used it in my old G4 500 and now I have a G4 Dual 1.42.

It was originally loaded with TDM cards...can I now load it with Accel Cards and will it work?

Digi can you comment on compatibility?

Also, if this won't work are there any special upgrade prices for sending in the old exp chassis and getting a new one?

Kind of hard to say without knowing what chassis you have.
Or what Pro Tools version for that matter.

Pro Tools 6.2 was the first version of Pro Tools that supported HD Accel systems:

...and these were the expansion chassis models supported with PT HD Accel and non-Accel systems on Mac OS X 10.2 (Jaguar):

I don't remember a hardware exchange program for any of the Digi expansion chassis, but there are none listed on the current hardware exchange list:
