Preparations#

When migrating from another software version or forum software, you usually want the new forum to be accessible via the same URL as the old forum. The following procedure is recommended for this.

  • Copy the old forum into a new subdirectory (for example backup) or rename the existing folder accordingly.
  • Upload the 3 installation files of WoltLab Suite into the directory where the forum should be accessible.

Example 1: Until now, your forum was accessed directly from your domain, for example woltlab.com. So log in to your webspace via FTP and create a folder backup. Now move all files and folders of your old forum from the main directory into this folder. Afterwards install WoltLab Suite directly into your main directory again.

Example 2: Until now your forum was accessible via e.g. woltlab.com/forum/. So log in to your webspace via FTP and rename the folder forum to e.g. backup. Now create a new folder forum and install WoltLab Suite there.

This procedure has the advantage that you do not have to redirect your domain or make path adjustments in WoltLab Suite later.

Note

During the installation of WoltLab Suite, in the step optional packages, select the package named WoltLab Suite Core: Importer to make the data import function available. Alternatively you can install the package later via package management.

Performing the Migration#

After successful installation you will find the data import function in the admin panel under Management → Maintenance → Data import.

Note

During the migration, the system tries to copy the IDs of imported contents so that data can still be accessed via existing URLs. The prerequisite for this is that the IDs are not already occupied. Before starting the data import, all data that may already exist in the new installation (e.g. forums, threads or posts) should be removed.

Database Access: The access data to the old database must be entered here. If you are not sure about the table prefix, you can always check it in phpMyAdmin. Usually every webhoster provides phpMyAdmin in his customer area.

Path to Installation: The absolute server path to the source forum must be entered here. By default the path to the home directory of the domain is given here. If you followed our example from above, you only need to add /backup to the path.

Depending on the size of your old forum, the data import may take some time. Please do not close or refresh the browser window during the whole runtime. For large forums it is recommended to use the import via command line.

After a successful data import, the data must be rebuild. To do this, call up Management → Maintenance → Rebuild Data in the admin panel and perform all actions in sequence.
