How long should a version control migration to TFS take?

  • [アーティクル]

I'm curious what you think.

Imagine you have an installation of Generic Version Control System with 500,000 items you intend to migrate to TFS.  Each item has, on average, 3 revisions of history.  So you have 1.5 million revisions.  And let's say that this was done over 200,000 changsets.  Also, if you want, let's say that all 1.5 million revisions amount to 6GB of file content.

If you were going to migrate that data, including all history, how long (in minutes, hours or days) would you expect that to take?

    Since this is a one-time operation, I'd be fairly flexible in terms of the time, assuming that the operation completes successfully the first time and doesn't have to be repeated. In other words, I would expect such an operation given those parameters to take up to 12 hours to complete on modern hardward and within a modern corporate LAN.
