Can anyone confirm or deny the following rumour?

The machine in question is a DECstation 5000, upgrading to a  5000/260
by replacing the R3000 chip with the more powerful R4000 .

With the new chip will the existing copy of Mathematica...
	1. work at all ?
	2. be correctly licensed ?
	3. have to be reinstalled ?
 	4. if 2 or 3 will the same password be valid ?

For  support at :

If the answer to any of the above is NO, will there be any cost involved
with obtaining the appropriate upgrade, in order to return to a properly
working Mathematica system? 

As the current kernel version is only 2.0, will such a cost be any more than
the normal upgrade cost to version 2.2 ?

Eagerly awaiting any replies,
	Ross Moore
