mysql -uroot -p1 db606 < db.sql;

Delete all database views (if any).
4. Unzip clean Liferay 6.0.6.

5. Delete all folders from 'webapps' (except 'ROOT' and 'tunnel-web'); delete jre from tomcat folder.

9. Create portal-ext.properties file:

jdbc.default.driverClassName=com.mysql.jdbc.Driver

jdbc.default.url=jdbc:mysql://localhost:3306/db606?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false

jdbc.default.username=root

jdbc.default.password=1


permissions.user.check.algorithm=5

image.hook.impl=com.liferay.portal.image.DatabaseHook

10. Startup Liferay 6.0.6. Wait until Liferay's upgrade process has upgraded database to 6.0.6.

11. Check if there is no " ' " symbol in resourcecode.name DB field.
Go to Control Panel → Server Administration → Data Migration. Click 'Execute' under 'Convert legacy permission algorithm'.

14. Change image.hook.impl to com.liferay.portal.image.FileSystemHook in portal-ext.properties file and restart server.

mysql -uroot -p1 db62 < db61.sql;

jdbc.default.driverClassName=com.mysql.jdbc.Driver

jdbc.default.url=jdbc:mysql://localhost:3306/db62?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false

jdbc.default.username=root

jdbc.default.password=1


passwords.encryption.algorithm.legacy=SHA

Step 3. Portlets and Themes Migration.

3.1. Migrate portlets from 5.2.3 to 6.2 version.

3.2. Migrate themes from 5.2.3 to 6.2 version. Make sure, that themeId is the same in 5.2.3 and 6.2 versions, otherwise themes will be not applied for pages.
