Data Migration in Liferay
If you are upgrading from a previous release of
Liferay Portal or if you need to
migrate your data from one system to another, the
Data Migration tab helps you
to do that without your developers having to write
custom scripts.scripts.

16. USING THE CONTROL PANEL
e
first section lets you copy your entire Liferay database from the current
database under which it is running to the database
you specify in this set of
fields. You’ll need to enter
the driver class name (and the driver will need to be
on Liferay’s classpath), the
JDBC URL of the database to which you’ll be copying
your data and the credentials of a user with access
to that database. Once you
have all of this information entered, click Execute to
copy the data.
e
next section helps you migrate your documents. If you want to move
off of the Jackrabbit JSR-170 repository to the file
system, or to the Jackrabbit
repository from the file system, or to any of the
other repositories supported
by the documents and media library, you can do so
very easily. Make sure you
have already set up your portal-ext.properties
file so the hook is properly
configured before running this migration. Select the
Document Library hook
that represents where you want your documents
migrated and click Execute.
Your documents will be migrated to the new
repository. You can then shut down
Liferay, make the new repository the default in the portal-ext.properties
file and then restart.
Once the data migration solution providers had explained to me the importance of the project, then I was capable of transferring the user data from one location to another. The services provided by your company are superb, and the regular suggestions had upgraded me with the latest information.
