Can I use Composer 6.5 with a Documentum 6.0 or 5.3 repository?
Yes, you can use Composer 6.5 with a Documentum 6.0 or 5.3 repository as long as you are not trying to install BPM artifacts or artifacts that leverage new Documentum 6.5 functionality, such as Smart Container (introduced after Documentum 6.0) or Aspects (introduced after Documentum 5.3). Currently, Composer 6.5 SP1 supports Documentum 6.5 SP1, 6.5, 6.0SP1, 6.0, and 5.3 SP6 repositories.
