Bug Description: Show-Stopper - Migration from HP-PARISC DS 6.21 to DS80 on HP-Itaninum
Reviewed by: nhosoi (Thanks!)
Fix Description: These are additional fixes for various and sundry problems:
1) If doing cross platform migration, just use the default db and changelog db dirs
2) If doing same platform migration, try to keep the db dir if the user has changed it.  It will usually be changed for a good reason, like moving to a separate device for performance reasons.  In order to see if the directory has changed, we need to "normalize" the path in the attribute so that we can compare it correctly.
3) Do not migrate the attributes nsslapd-db-private-import-mem and nsslapd-import-cache-autosize - just use the new default values for these
4) Do not migrate nsslapd-allidsthreshold - this has been removed
5) Add additional error checking and handling when migrating the local.conf information.
6) Change the brand in the sie and isie when migrating.
7) Update the Group in console.conf during migration.
Platforms tested: HP-UX 11.23 IPF64
Flag Day: no
Doc impact: no
QA impact: should be covered by regular nightly and manual testing
New Tests integrated into TET: none
