Suppose I have a portlet written for Liferay 5.2.3 and I want to run it on Liferay 6, how can I do that?

1. download sdk.
2. create new portlet plugin in the sdk.
3. copy files from old portlet code to the new portlet.
4. build the portlet, resolve any issues that come up.
5. deploy the portlet, resolve any issues that come up.
