Liferay migration from one server to another help required. Can anyone share there steps for migration of Liferay portal 5.2.3 from one server to another. I am using Windows + Tomcat + MySql.

I have uploaded whole tomcat folder to the new windows machine and imported the database too with the corresponding change to the configuration file like Database details.

But after starting the tomcat server it is showing some error like “Unable to load repository http://plugins.liferay.com“. Any idea why I am getting this error ?

    These are the steps that I have followed and able to migrate the Liferay successfully:

    1. Take the backup of Liferay files and database from first windows machine.

    2. Install the same version of Liferay (Say Liferay 5.2.3) on second windows machine.

    3. Shut down Liferay.

    4. Import the database on new system.

    5. Add portal-ext.properties with relevant entries. (e.g Datbase Name, User Name , Pasword etc)

    6. Add \liferay-portal-5.2.3\data\document_library files from old machine.

    7. Start the tomcat. It will automtically do the rest.

    NOTE: In the above method I have not deployed Theme and custom plugins etc, you have to deploy Theme and custom plugins also that are used on old system.
