Importing Liferay Projects of Different Versions

Let's say we have a Liferay project developed in Liferay version 6.1.1 and you need to import the project in Liferay 6.1.3.
Things that need to be changed are:

1. The licenses and liferay-version properties in the liferay-plugin-package.properties file.
2. You may have to change few classes or methods that may not be available in the new/old version.

I have a Liferay CE v6.1.1 portlet that needs to be imported in Liferay EE v6.1.3. In the <portlet>/WEB_INF/liferay-plugin-package.properties file, we find the below properties.

licenses=LGPL
liferay-versions=6.1.1

To import the project in your Liferay IDE, easiest way is to open up the <portlet>/WEB_INF/liferay-plugin-package.properties file from an existing portlet and copy values of licenses and liferay-versions properties to the project that needs to be imported.
I'm using Liferay EE v6.1.3 and found the below values:

licenses=EE
liferay-versions=6.1.20+

We'll have to update the values in the portlet that has to be imported.
Feel free to post Comments.
