Hey, I am looking to upgrade my v4 installation to Beta6 (well, master - to overcome the mem leak mentioned on the wiki). The end goal is to be on Beta6 with the Samba4 on a new host in a remote location - but preserve the same domain, accounts, SID's, etc. I see on the wiki it mentions that I should get advice before trying this from this list - so anything you can provide me with would be appreciated! I pencilled out two options (are either feasible?): 1) Create new remote host, install v4 B6, join to existing domain, and shift FSMO roles. Then, remove v4 A14 from the domain - and hey presto. 2) Remove v4 A14 from the machine, but preserve databases. Install v4 B6, and attempt to upgrade the databases somehow (but I wouldn't know how to start with that). The current v4 A14 install was not upgraded from an earlier version - it was installed fresh. Exact version is 4.0.0alpha14-GIT-e8bae4c. Thanks for any advice, Dan
