Migrate from Mediawiki to Confluence




i need to migrate a big Mediawiki (135.000+ Sites) for a customer to Confluence.


The only tool available seems to be UWC, 

but the tool simply stops at 7-11% randomly with Conversion Status NONE.


I cloned it from GitHub, but 3 dependencies are broken, so I can't fix it.


I converted it with UWC and a php script. 


Is there another way to do it?

Hi All,

At Xoriant we offer a paid service to migrate MediaWiki to confluence and we have already done this for our customers with 1000 plus pages. Please reach out in case you want to avail this service


Vinish Nair

need to migrate a Mediawiki to Confluence too. In my case I have few pages to migrate (less than 1000).

Atlassian says that UWC is no longer available.
You comment here that there are scripts in Python, Php or GitHab to migrate it.

Could you share any example of these scripts?


I can provide the UWC tool and the php script I have used.

I will upload it when I'm back in office on monday.


U need the php script to create the structure before importing it via UWC.

Hi @Marcus V_ ,

We are looking for the same functionality. Would appreciate the tool and the script!!AiAlKGax1tZRgegsCcsHZ5T3_l09SQ?e=orXAGm

The php converter is currently not on my working machine.

I need to get it from our old backup server.

UWC is what we use, but we have forked it and made a bunch of changes to it. It's no longer maintained by the original author.  I've seen people use python, but I don't know if they wrote everything from scratch or used something readily available. Sorry I don't have better news for you.

Thanks for the answer.

I will try to find another solution.

@Marcus V_ Have you found something? :-) 

@Hiwad Said [venITure] 
Yes. The main problem was the java gui.

Using some scripts to run the program in the command line I was able to import all sites into my confluence instance.

For the media wiki I needed to migrate it took 18 hours for the conversion and upload.

Some problems also occured running two seperate java version on the machine where the tool was running.


I can provide the scripts and some of the documention I wrote for the customer on monday.


Sorry for the pretty late response.

hi @Marcus V_ 
we have also tried migrating from MediaWiki to Confluence,
pages and images (partially) were migrated fine,
the issue we face now is with the xml parsing

 we used UWC V. 4.0 and Confluence 7.1.9 

did you hade any parsing issues on your migration and was able to solve that ? 

Thanks in advance. 


hello  @Alon Shaniv ,

Could you please share with me the UWC cause it's no longer available on the marketplace.
