I've been the SVN and Accurev administrator for a time. Accurev took a long time to grow on me - about six months, but I like it now for a corporate enterprise environment. Here's a few things to consider.
Pros:
- Personal code history
- The code changes are kept on the server when the users performs a keep. The keep is personal to the user and doesn't distribute to other users until a promote command is issued.
- The code performed by a keep is kept on the server and available even if the user performs a revert operation.
- In most cases, promoting the code to higher streams for distribution is fairly simple.
- Administration is fairly simple
- Installation works well
- Performance is much improved on version 5.3 which changed the backend to a PostGres database
- The CLI is rich and extensive
Cons:
- A real clunky user interface
- Resolving overlaps can be complex, just like conflicts in SVN
However, like any complex tool, your appreciation will increase the more you understand and know about it.
