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

[Lelio Fulgenzi]

I wouldn't be changing the hardware to a 7845 I would be adding pieces to my 7835 to 'make' it a 7845.

  Afar as I understand it, it doesn't matter what the hardware is (as long as the installer recognizes it as an MCS)  if you have a 7835 now, you run with that, when you move to the 45, you would use the bars utility to backup your CCM configuration, then load the 45 (Using the recovery mode) and restore the config, the installer would see it as a 45 and install advanced server, then when you restore the config you are up and running...As far as I know it doesn't care what OS you have...

  Of course I've never gone from one MCS to another, I've only gone to the same MCS so I could be wrong but I don't think CCM cares....

  can i change this? is it not advisable then to plan on buying a 7835 with intentions of upgrading it to a 7845 later?

    should still be recog as a 7835 by a text string in the bios.
    7845 install gets Windows advanced server for > 4GB memory addressing.

    I'm sorry if I asked this before, but I'm just wondering what upgrade options I might have if I buy a 7835 now and want to upgrade it to match 7845 specs in the future? 

    From what I gather the two systems are exactly the same except for memory, extra CPU and extra hard disk space. I'd probably buy a spare CPU off the bat since it would be hard to match later.

    If I upgrade at a later time, will the hardware detection disks recognize it as a 7845 and format the disks and install the image appropriately or will it sill think it's a 7835? If it only recognizes it as a 7835 is there something I can switch (software/hardware) to make it be recognized as a 7845?
