Gitorious upgrade from 2.0.0 to 3.1.1

We have a Gitorious installation that is used as the main code repository and runs on 2.0.0 When we attempted to use the upgrade path outlined in https://gitorious.org/gitorious/pages/Upgrading we had problems because the original installation appears to be unable to upgrade to 2.0 -> 2.1

We have also attempted to clone the code from the original installation, change the origin in the .git/config file and push to the new gitorious installation. Although this works there are a couple of problems:

1. Some of the history is lost
2. Only a single branch is pushed to the new repository
3. We have about 150 different projects

Has anyone had success with upgrading Gitorious from 2.0 -> 2.1 or pulling large numbers of repositories from one version of gitorious and pushing them to a later version.

just setup a new installation, pull the repository, and then just push to the new. this will push the complete history. git remote set-url <new url>

Push local Git repo to new remote including all branches and tags
