There are a set of new IDs that will be created and they will need the
same access rights as their predecessors.    If you have a SYSPROG group,
for example, you will need to connect MAINT630 to it.   INSTUPGR has no
idea whether you have done that.  I think products like zSecure can
replicate permissions quickly and easily.

However, if you have the DIRMAINT-RACF connector turned on, then the
creation of USER profiles will be automatic, as will their VMMDISK
profiles and permissions.  I.e. the moral equivalent of DIRM FOR DIRMAINT
AMDISK will be generated automatically.

So only things outside the realm of the DIRMAINT-RACF connector (e.g.
group membership) need to be handled manually.  That's wouldn't be all
that much, but it includes LINKs!   The privileged form of DIRM FOR <user>
LINK should be driving a RACF connector, but it isn't.

>From an ESM perspective, realize that changing the indirect LINKs in MAINT
to point to MAINT630 *may* drive a lot of permission changes.  E.g. People
who LINK MAINT 490 today have authorization to MAINT620 490.  Now they
need MAINT630 490.  How to get it?  To give RACF examples:
- VMMDISK class is inactive, so it's CP's problem.  (Puh-leeze)
- GLBLDSK entry in HCPRWA (cough)
- Global Access Checking table entry in RACF (Good for this particular
case)
- Access via discrete VMMDISK profile (SOP)
- Access via generic VMMDISK profile (I don't recommend this for mdisks)
- Access via OPERATIONS authority (boo! hiss!)

A DIRMAINT-RACF connector could be added to help with LINK processing, but
that discussion needs to be had with the Support Center.
