The backup file is 256M. Memberships are 1507480, in 90908 groups. The subject source is edu.internet2.middleware.grouper.subj.GrouperJndiSourceAdapter, but maybe I will change it and compare.

What is the filesize of backup.xml ? How many memberships do you have ?

I've been able to xmlimport with Xmx=1024m, and we have ~1 million
memberships (select count(*) from grouper_memberships), and our xml
export is ~175MB.

What source adapters are you using ?

This doesn't answer your question, of course.

Congrats on the fantastic new release, nice stuff. I am doing upgrade
rehearsals under Method 1,

"./bin/ -xmlimport GrouperSystem backup.xml"

But it always uses all of the memory. I increased it to 4GB, but it still
actually commits that much. Before moving on to method 2, I thought I'd
ask, is there anything I can do reduce it?

Obviously, this is the actual error:

java.lang.OutOfMemoryError: Java heap space
