Customer has a Definity csi that has died. All the lights on the processor are red and when connected via laptop the only options you get are "view alarms" and "reset system(4)". The alarms only show a major alarm on the processor.

Their IT guy seems fairly proficient on tracking down parts but wants us to tackle replacing the processor.

The current unit is a V4 and the new(er) one looks to be a V9.

Are there any issues in swapping the processors, ie licensing, features, etc?

Can the old PC card be used or new one required?

Any way to recover old backup from PC card? I assume not because of the different software versions.

Thanks in advance for any suggestions.
