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


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

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!

Thanks in advance,
