====== WPAR upgrade / migration ======

OS upgrade is always done from LPAR (Global) except particular case like root WPAR, or version WPAR.

===== WPAR upgrade =====

First upgrade the Global LPAR, then use the command syncwpar
  syncwpar -A : for all WPAR
  sycnwpar wpar1 : only for the wpar1
  syncwpar -T wpar1 : for debug mode
  
===== WPAR migration =====

First migrate the Global LPAR for example from AIX 6.1 to 7.1.

Then do a syncwpar which will start a migration (using background commands like migwpar, syncroot) on the WPAR from AIX 6.1 to 7.1

**If WPAR migration failed**
In case of partial migration, migration will not return a right exit code, the the WPAR can't be started, except in maintenance mode : 
  startwpar -m wpar1
  
If you retry a syncwpar, you have message like:
  WPAR is not migratable.
        wpar1 version = 7
        lpar1 version = 7
        
In this case, ERROR WPAR is at same level as Global LPAR, but syncwpar can't be redo, then do:
<cli prompt='#'>
# mount /wpars/wpar1
# ODMDIR=/wpars/wpar1/etc/objrepos odmdelete -q name=bos.rte -o lpp
# umount /wpars/wpar1
# syncwpar wpar1
# start wpar1
</cli>
