WebSphere Portal V8 migration from V7


This week i am working on a migration project.  Everything was fine until i ran

 ./WASPostUpgrade.sh /waspreupgradebackup -profileName wp_profile -oldProfile wp_profile -username wpsadmin -password ****** -includeApps true -backupConfig false -javaoption -Xmx3056m

MIGR0272E: The migration function cannot complete the command

I run again the command with Xmx4096m but the command doesn´t run anymore and the logs show that the parameter -includeApps is not valid.

The solution was

1 – Delete the wp_profile
2 – Delete the JCR index collections
3 – Run WASPreupgrade on the source portal
4 – Recreate the wp_profile on the target machine
5 – Run the WASPostUpgrade with Xmx510m
