4221.0. "MCM V6 and MAM V4.x compatability" by CSC32::B_GOODWIN (Brad Goodwin - NSIS) Wed Feb 19 1997 17:37

    Hi all,
    
    With ClearVISN V2.0 MCM V6, will it be backward compatable to hubs 
    running V4.x MAM code or will you have to run V5.x MAM code. Also, 
    same question for ClearVISN X1.1-20 MCM X6.0-20.
    
    Thanks,
    Brad

4221.1Not officially supported - upgrade hub to V5.0NETCAD::MILLBRANDTanswer mamThu Feb 20 1997 10:0416
Hi Brad -

Well, it will look okay with a "pure" V4.2 hub - one whose modules are at
compatible versions.  However, if the hub contains modules not supported
on V4.2 (particularly VNswitches), MCM V5.1/V6.0 has been seen to paint
"imaginative" LAN Interconnect screens.  Backward compatibility was not
a release goal nor is supported.

MAM V5.0 will be available at the same time as MCM V5.1, so it will be
best to upgrade the hub, then the NMS.  The release notes say this (about
ten times).  If you have any customers who used VNswitch seed units with V4.2,
make sure they are aware.

Thanks,
	Dotsie

    Thanks Dotsie,
    
    I was just asking because my customer is ordering alot of VNswitches
    and they have alot of hubs. The hubs with VNswitches will get upgraded
    to MAM V5, but they have alot of hubs without VNswitches running MAM
    V4.x that might take some time to upgrade because they are spread all
    over the country. I wanted to find out if they could use MCM V5.1/6.0 
    on those hubs until they can get them upgraded.

Unfortunately, it doesn't matter what modules are in the hub.
MCM 6 cannot manage a V4.x hub. I'm not a clearvisn person
so I can't remember all the version numbers, but I know the 
latest clearvisn MCM cannot manage a v4.2 hub. You have
to stick with the MAM / MCM combinations that are shipped
together on the cdrom.

4221.4very important to keep correct MAM/MCM pairsNETCAD::MOWERSat Mar 01 1997 23:0221
  Mike is exactly correct: use MAM/MCM combinations as they are shipped
  together - extremely important.

  MAM 4.2 -- clearVISN 1.0
  MAM 5.0 -- clearVISN 1.1a

  I understand that for large installations at any time you will have some
  hubs at 4.2 and some at 5.0.  This will require you to have two clearVISN
  installations: clearVISN 1.0 and clearVISN 1.1a, and you will need to 
  keep it straight which clearVISN with which hubs.  (Since it is difficult
  to run two clearVISN versions on the same PC, you will need 2 PCs during
  the transition).

  I understand the great trouble this causes;  we, (specifically, I) are/am
  looking into ways to at the very least, improve this.
