Migrating data with backup and restore methods
These migration methods require that the file systems or logical volumes that you are backing up are in a quiescent state. Use the following information as a guide to determine when to use backup and restore methods to migrate data on UNIX-based host systems.
About this task
Typically, you run backups after hours when there is minimal system use and you can shut down databases.
Some databases require that you export the data before you move it between file systems or logical volumes. You must then import the data on to the new file system or logical volume. You might have to reconfigure the database to point to the new data locations.
