To IPL VM/ESA while VM/XA is still the production system,
 
1)  Get an updated directory on the VM/ESA sysres volume.
    a)  Update $DIRCTL$ (this is just like a userid in the directory)
        - DIRM LOCK $DIRCTL$
        - DIRM GET  $DIRCTL$
        - Change the DIRECTORY 1120 3380 DRES00 *70119-3090 VM line
                  to DIRECTORY  680 3380 RESE01 *70119-3090 VM
        - DIRM REP  $DIRCTL$
    b)  Write it on the sysres volume.
        - LINK RESE01 100 680 MW
        - DIRM BACKUP (to get DIRMAINT to write a single-file directory)
        - IPL CMS9    (to pick up the VM/ESA DIRECTXA module)
        - RR DIRMAINT 193 (to get to that single-file directory)
        - DIRECTXA USER BACKUP X
 
2)  IPL 680, the VM/ESA SysRes pack.
 
3)  Once it's up, save a current version of CMS before bringing up
    the service virtual machines.
      SAVECMS CMS
 
4)  Purge all the old accounting data from the last time you were up,
    else you screw up the accounting system.

------------------------------------------------------------------------
To go back from VM/ESA to VM/XA, you need to copy all the spool files
from the VM/ESA system over to the VM/XA system.  I've found the
easiest way to do this is with VM/ESA running second-level under VM/XA.
 
1)  Change $DIRCTL$ back to 1120 and DRES00.
 
1)  Shutdown VM/ESA.
 
2)  IPL 1180, the VM/XA SysRes pack.
 
3)  Once up on VM/XA, logon to RICKLANE and run the VMESA EXEC.
    This will link all the VM/ESA system spool, page, & sysres packs.
    Follow the instructions the exec gives you, namely
    - DEFINE STORAGE 100M
    - TERM CONMODE 3270
    - IPL 680
 
4)  Once VM/ESA is up second level, SPTAPE the spool files over.
    You'll need to do up to 4 sets of SPTAPE commands, reader files,
    reader files with user holds on them, printer files, and printer
    files with user holds on them.  If there aren't any files in a
    particular category, then of course you don't have to SPTAPE them.
    For each category,
    - Put a scratch tape on a tape drive
    - Attach FE0 RICKLANE (or whatever drive you're using.  You might
                   choose to use 3 or 4 drives, one for each category)
    - On RICKLANE talking to VM/ESA, SPTAPE DUMP FE0 R ALL       REW
                                  or   "     "    "  R ALL USERH REW
                                  or   "     "    "  P ALL       REW
                                  or   "     "    "  P ALL USERH REW
    - DETACH FE0 RICKLANE LEAVE (so the tape doesn't get unloaded)
    - From VM/XA, SPTAPE LOAD FE0 R ALL       REW
               or   "     "    "  R ALL USERH REW
               or   "     "    "  P ALL       REW
               or   "     "    "  P ALL USERH REW
 
5)  Carefully shutdown the VM/ESA system (not the real, VM/XA system).
