Hi all,

we've just started the process of upgrading our old Grouper 1.5.3 instances
to Grouper 2.2.

Have managed (I think) to do an upgrade straight from 1.5.3 to 2.2 on our DEV

We're also using Java 1.8 and Tomcat 8 and so far all seems to be well (after
a few tweaks which from the mailing list also have to be done for Tomcat 7).
We're in the process of setting up PSP to provision Open LDAP, so once we
have all the upgrade done and dusted I'll post back to the list with any
observations and tweaks we had to make to get things to work.

I have a question though regarding the migration of old types. We had a
custom group type which we stored a gid value in, and a grouper hook which
adds the custom group and then sets the gid value.

Post upgrade, I can see all the values in the grouper_attributes_legacy table.

However I'm not entirely sure what to do at this point. Do I need to now
create a new attribute, assign to all groups and port the legacy values over?
Or should I be able to query the legacy attributes still? They don't show up
in the UI, and I don't appear to be able to get at them using Grouper Shell,
but it's entirely likely that I'm missing something.

I had a look at which
pointed me to the right place in the database so I can see I haven't lost

Any pointers gratefully received!
