The document describes migrating database files from the "+DATA01" disk group to the new "+DATA02" disk group. It involves creating the new disk group, identifying database file locations, copying files to the new disk group using RMAN backups, and switching the database to use the new disk group.

1. ASM DiskGroup Migration from “+DATA01” to “+DATA02”
