Let me start by saying this. It is possible to migrate all the data to XenFORO, the question comes down to how much time, money, and effort you wish to spend? This weekend I am going to attempt to migrate XLNation Forums to the XenFORO forums. The wife is away and I have lots of time. I will use the Drupal >> phpBB3 >> XenFORO migration path using FREE software. This would not be the final migration but will demonstate if it can be done. If it works we can exam the results and see how many problems we have to deal with. We can decide if it's "good enough" or consider other options. Now notice I did not mention the City Journals or XLEX, that is a whole other can of worms I will talk about shortly. The City Journals and XLEX. That part of XLNation is not a user Forum but an addon module of Drupal (at least I think it is) with its own database. The resource manager of XenFORO is an add-on as well. There is no migration path available via free software that I can find. 1. The XLEX could easily be manually recreated on the new site, heck I did a few myself to test. Get a few people together and knock it out. Granted all the discussions would be gone but the important stuff would be there. Moderators could easily "re-assign" the resources to the original owner if they still exist once they get on the new website 2. There are tons of City Journals and those are way more complicated since the discussion threads are a big part of the CJ experience. I dont see anyway to manually migrate them without third party help. I know of a webmaster that converted from Drupal to XenFORO successfully using a company called gConverter. I have contacted them and now I am waiting for a formal price quote. Their price quote is based in part on the number of users, topics, posts etc to be migrated. Right now we are looking at around $200 - $250. If we purged the users database the costs would drop a lot. I am willing to cover this cost myself. The issue is migration of CJ and XLEX data, that will cost even more since its a specialized migration. The community will need to decide on the value of the CJs, and the XLEX discussion data vs the cost to migrate. This cost I cannot cover myself. Some thoughts: 1. Is it really necessary to migrate 78,000 + users? I would suggest purging out anyone that has not logged into their account in the last two years? 2. Stick with Drupal and just upgrade the Software. That would be easy.
