Hello all,
i just finished an upgrade of OD from 5.6 to 6.1 and i just want to put some info on here for anybody who might need them in the future.
the upgrade is just installing OD 6.1 on top of 5.6. there are no changes made but in the deployment script files, if you use

\Interwoven\OpenDeployNG\conf\dtd make sure you change it to OpendDeployNG\dtd\conf.
and of course change the odnodes.xml.new61 to odnodes.xml and rename the old one .old and the same for all the config files.
