Now that we have repaired the database we are ready to configure Liferay 6.1 to prepare it for the upgrade. For the upgrade I recommend that you deploy only the core Liferay installation. This keeps the number of things that can go wrong to a minimum. You can then later deploy any additional Liferay and custom portlets.
For the upgrade the “passwords.encryption.algorithm.legacy” property needs to be set in portal-ext.properties.
Additionally I would go ahead and set the following properties as we determined they are needed for Liferay 6.2 to run smoothly.
You will also want to acquire a new license for your server that is compatible with Liferay 6.2 if you are using the enterprise edition. Additionally I highly recommend backing up your database for this upgrade. If there are any problems during the upgrade you can restore the database, fix the issue and start again. Once you startup the server you shold start seeing entries similar to the ones below. If something goes wrong you will likely see many additional errors.
If the upgrade process goes smoothly you can shutdown the server and drop the license file into the deploy directory. You should now be able to connect to your new version of Liferay. There is still more to do. In the next part we will be configuring Solr 4 to work with Liferay 6.2.
