Basically, the workaround involves moving all files associated with a 
running CP from the old host to the new host. Pretty simple, but if you 
don't pay attention to the details, it can get you.

For each CP, move these files:
    /usr/fox/sp/files/DB<cplbug>.UC     (checkpoint file)
    /usr/fox/sp/files/BB<cplbug>.UC     (backup checkpoint file)
    /opt/fox/ciocfg/<cplbug>            (entire directory)

For each compound in that CP, move these files:
    /opt/fox/ciocfg/<compoundname>      (entire directory)

That's about it. We don't use SOE, so I'm not concerned with those 
files. And of course, you want to remove these files from the old AW 
once you verify that you've copied everything over to the new one.

To move the CSA from one AW to another, check out the CSA utilities in 
/usr/fox/csa.

There used to be a problem with not being able to download FBM if you 
change the host of a CP (until the CP reboots), but either this problem 
is fixed already, or there is a workaround. See CAR #9468, among other things.

If I missed anything, I'm sure it'll be corrected. (I'm at home and not 
in front of one of my trusty AWs, so my brain already went into 
shutdown mode a while ago.)

Remember Alex Johnson's mantra: free advice is worth what you pay for 
it. Especially when it comes from a guy giving it on his free time. ;-)
