[cisco-voip] Upgrading 7835 to 7845 - what options do I have?

[Mike Armstrong]

It's not that simple.   Here's a summary of my experience installing 4.1(3):

We have a spare
DL380-G2 we use for testing and staging which was purchased late in the G2's
life, and came with 2 1400MHz processors.  When I started a clean install of 
the 4.1(3) Subscriber,
CD1 identified it as an MCS7835 OK, but CD2 (apparently because of the
1400MHz processors (not the presence of the 2nd processor -- this works OK
on a dual-processor 1266MHz system)) decided it was an MCS 7845, and called
for CD10 rather than CD9 to install the OS.  Since we did not have a 2nd
mirrored drive pair, the install script failed looking for the 2nd drive.
