Re: [xwiki-users] Upgrading xWiki

Hi Mbas! I started to write this message weeks ago, and only now find time enough to finish and send it. I hope it still makes some sense for you or/and anybody else. I'm afraid, as usual, I've not an easy answer for your question but I am, and I'm also sure many others, interested in how you are going to face the process. Migration is always a hard task as, very frequently, plain old wikis are full with "ad hoc" not easily replaceable/migrable solutions. Some years ago XWiki guys helped me to move a 1.x XWiki installation to a XWiki Enterprise 2.4.30451 server and, since 7.x appeared, I've a "peding upgrade" from that 2.4.30451 to a new 7.x server. During the last months I've been documenting the process to upgrade within the 7.x series, and now I feel more or less confortable with it. Here some notes I would like to share even thought they are still kind of a mess... http://portal.idisantiago.es/xwiki/bin/download/ICT/UpgradingXWiki/upgradin… I'm not sure if I'll be able to move to parameters all variable items and construct a script, but I'll keep trying! Also, I'm afraid any migration/upgrade process is very related with the RDBMS, the application server and the web server (if any) of each installation. My take now is that in a XWiki migration from an old version to a brand new installation we have to design/follow a strategy more than expect to have a fully equivalent upgraded installation. For instance, I would like to: 1) As users and groups are the core of the system, I would like to "move" my old XWiki community, the one installed in the 2.4.30451 server, to the brand new 7.x box, get all users authenticating in the 7.x box and having access with this login to the "legacy 2.4.30451" box. 2) Once I get this done, I'll frozen my 2.4.30451 community and only allow it to growth in the 7.x installation. 3) Contents will be exported/migrated on a per-demand/per-opportunity basis. While 2) and 3) are easily implementable, I''ve no idea about how to reach 1). Any comment, criticism or idea will be more than welcome!
