OpenLDAP upgrade 2.1 -> 2.2

[cantao]

Dear Friends:

I want to upgrade my current openldap server (clients upgraded ok) from 2.1.26 to 2.2.28. The ebuild gives me 12 steps to backup my database, update openldap and restore the database.

As I am not an LDAP expert, and the guy that set up the system is no more available, I feel *very* unconfortable doing this, given that I can simply render the whole system unusable.

So the question is: did anybody upgrade openldap succesfully? Any troubles? Hints?

Thanks a lot in advance, Cantão!
