Migrate your DNN gallery to 3.2

Back in March we announced there will be no further releases of the Gallery Server Pro DotNetNuke Module. Since that time a number of you have asked about migrating your DNN gallery to a stand-alone instance of Gallery Server Pro. Some of the data in the DNN gallery is specific to DNN, so we can’t use the built-in migration path. But a few days ago a customer running clockdoc.org hired me to migrate the data, so I was able to dig into the details about what was involved. It’s actually pretty easy so I thought I’d write up the steps so you can migrate your own DNN gallery.

As an alternative, you can hire me to do the migration. See the end for details.

  1. Start by logging in to your DNN gallery and turning off the auto sync feature if enabled (it’s on the Albums page in the site admin area). This prevents a sync from kicking off and deleting records before your new gallery is fully set up.
  2. Go to the Backup/Restore page and make a backup of your gallery data.If you aren’t using the user albums feature and your gallery has only a few users, uncheck the option Export user accounts before making the backup file. This option includes DNN roles like Translator (en-US) and Unverified Users, which you really don’t need in your new gallery. However, it also includes user profile data such as the user album assigned to each user, so you’ll need this data if you want to transfer the user albums.

    NOTE: I haven’t tested a DNN migration that includes the user accounts, so there may be unforeseen obstacles or it may not work at all. Let us know what you find.

  3. Install a new instance of the latest version of Gallery Server Pro using either SQL CE or SQL Server and configure an admin account.
  4. Copy the media files from your DNN gallery to the location you want to use in your new gallery. For example, the default media location is the gs\mediaobjects directory of the web application. If you have multiple galleries, you’ll have multiple locations.
  5. Log in to your new gallery and go to the Backup/Restore page. Restore the backup file you made in step 2. Once complete, DO NOT click anything until completing the following steps.
  6. In the database of your new gallery, manually delete all records in the GalleryControlSettings table. If using SQL Server, use a tool like SQL Server Management Studio. For SQL CE, use a tool like SQL Server Compact Toolbox.
  7. Manually delete all records from the GallerySettings table where SettingName=’EnableDotNetNukeSearch’ and SettingName=’PortalId’.
  8. In the GallerySettings table, look for the records where SettingName=’MediaObjectPath’. There will be at least two – one for the template gallery and one for your actual gallery. You can look in the Gallery table to figure out which gallery is the template gallery (it’s the one where IsTemplate=true).Update the one for the template gallery to something like ‘gs\mediaobjects’ – this is the default path that is used when you create a new gallery on the Manage galleries page.

    Update the path for your actual gallery to the place where you copied the media files earlier. If you have multiple galleries, update the path for each gallery. If you want, you can skip this step for now and instead do it on the Media Objects – General page, but you will get an application error if the gallery can’t find – or create – the path defined in the setting.

  9. Now navigate to your gallery in the browser. Because we emptied the GalleryControlSettings page, the gallery will assign the first non-template gallery to the default.aspx page. If this is incorrect, use the Manage galleries page to pick the right one. If you have multiple galleries, you can create additional pages and assign them to each gallery as needed.
  10. If you use the auto-sync feature, turn it back on.

That should complete the migration. Enjoy your new gallery and all the cool new features in v3!

If you don’t want to hassle with it yourself, hire me to do the migration. It is priced at four hours of custom work ($320). Contact me if you’re interested.
