Migration script to migrate from Gallery2 to Zenphoto.
This script will help you migrate from Gallery2 to Zenphoto. It is crude but effective.
To arrive at the following script I mashed together some bits and pieces that others had published online, added some of my own perl glue, and came up with a Frankenstein script that did 85-90% of the work for me.
You'll need perl and the following perl modules to use the script:
- DBI
- DBD::mysql
When I ran the script, it was against Gallery2 version 2.3.X of Gallery2 and Zenphoto version 1.4.3.
IMPORTANT NOTICE: I take no responsibility for any data loss you experience as a result of running this script. Caveat emptor. You get what you pay for.

Start by reading this entire document, especially the Gotchas section below and the IMPORTANT NOTICE above.
-
Now back up your Gallery2 data, both the albums and the database. Remember the IMPORTANT NOTICE above.
-
You should then back up your Zenphoto database and any associated albums.
-
Modify the variables at the top of the script to be appropriate for your environment.
-
Run the script. Watch the output to ensure that it's doing what you think it should.

Send me any feedback you have at djb@bogen.org.
There are a couple of gotchas involved with the script. Reading through the code is definitely worth your time if you're at all worried about the results or if your installation is in any way non-standard.
The biggest gotcha you might encounter will be if you have multiple albums in Gallery2 that all have the same name. In that case, you'll find that the contents of the albums will all end up concatenated into one album. To avoid that problem I recommend that you temporarily rename one of the conflicting albums to a unique name until the conversion is complete. Once the conversion is complete you can rename the album again back to its original name.
This script will only import JPEGs and albums. If you're trying to import GIFs, PNGs, Flash, or anything else you'll need to modify the appropriate regex to recognize the file extension.
The biggest problem I had with the script is that I didn't build in the requisite logic for the script to intelligently choose between the summary and description fields as the source for the photo caption. At some point during my use of Gallery2 I had switched from putting information in the summary field to the description field. As such, I had to choose which of the two fields I wanted the script to import for me and then hand-import the remainder. It is likely that you won't have the same problem.
In addition, if you’ve used any of Gallery2′s tags (to add a link to a field or bold some text or something) this script won’t recognize the tags and fix them. You can probably pretty easily fix all those problems with a few regexes in strategic places, but I only had a few of those tags in my own data so it wasn’t worth the time to build that into the script.
