I'm in the process of doing an upgrade from Grouper 1.3 to Grouper 1.6.1 using the first method. I dumped some groups in 1.3.1 and restored them in 1.6.1 using -xmlimportold. I dumped a stem immediately under the root using -name, and no other options. I didn't use any options on the import command.

I found that group members of groups were not being restored. I checked the dump and it looks fine, with correct entries for group members of groups. The groups to be added as members already existed, but the log showed them not being found. The problem seems to be in the restore program,, and this change fixed it for me:

< return this._getSubjectById(id, type);
> if (type.equals("group")) {
> return this._getSubjectByIdentifier(idfr, type);
> }
> else {
> return this._getSubjectById(id, type);
> }

I wouldn't expect the restored group to have the same id as the original group (unlike people, who do have the same id), so I'm wondering how this was intended to work.

There are two upgrade methods:

1. Export XML, then import into the version you would like (in 1.6, the xml format changed, but you can still import the old with
./ -xmlimportold GrouperSystem export.xml

However, Im not sure all the lastUpdated dates and minor stuff like that is
maintained. Also not sure about group descriptions (this was fixed in some
version, not sure which).

2. Do all the individual upgrade steps.

I went from 1.4 to 1.6 and did the individual steps. It was time consuming
though. If you want to give #1 a try, go for it, and check the data

Is it possible to upgrade from Grouper 1.4.2 to 1.6.1 without
stopping at 1.5.x?

What would be the best strategy?
