Migrating Liferay installation to different location

Imagine a scenario when you have a Liferay installation, but for various technical reasons, you have to move it to an other computer or just to a different folder. The other components of the system are not affected, the db connection, and all the connecting legacy system remain on the same location.

If the system setup is complicated enough, and the time frame is narrow, one of the simplest solutions is to just simply migrate the files to the different location.

Of course, some things should be done before this migration takes place. In this example, the Liferay version is 6.0.5 and is bundled with Glassfish 3.0.1.

• The first thing to do is to delete content of the /domains/[domain-name]/generated-sources directory. This directory can be huge (several gigabytes), and it is a generated content used for caching, so there is no point in copying the data, it will be generated again, thus small performance decrease might occur during the first opening of a page.
• The second important task is to delete the content of the /domains/[domain-name]/osgi-cache directory. If this directory is not emptied, then the Glassfish domain cannot be started, because the osgi-cache holds references for the absolute paths of some of the osgi jars.

After this two deletions are made, the Liferay installation can be moved to the new direction and if no other configuration is required (depends on the environment), it can be started safely.
