Liferay 6.1 with existing database

[Namrata Hangal，修改在11 年前。]

We have setup Liferay 6.1 GA1 CE on jBoss 5.1 successfully using the default hsql.

The next step is to connect the instance with an existing DB2 database.

Now the catch is that, the DB2 instance has all tables and data as per Liferay 5.2.3.(our previously created portal). We cannot create new database and must reuse the tables/data. Any changes to database may result in our live site collapsing.

How do I go about connecting 6.1 with the existing database?
I'm sure the db schema is different in 6.1 compared to 5.2.3. So what should be the first step?

Can anyone outline the steps to be followed?

Thanks!

Do several liferay upgrades to update your database. I think you'll have to upgrade to 6.0 and then to 6.1.

Thanks Hitoshi.

Can you point me to any documentation?

Hi Namrata,

Place these values in the portal-ext.properties along with any other older properties value.

#
# Input a list of comma delimited class names that implement
# com.liferay.portal.upgrade.UpgradeProcess. These classes will run on
# startup to upgrade older data to match with the latest version.
#
upgrade.processes=

have a look at the portal.properties for the list of all the classes.
