P4Convert: User Guide (April 2015)

Revisions are converted in full, creating a Perforce journal and set of archive files. Once replayed, the resulting conversion is just as if the changes had always been in Perforce. The results can be merged into an existing Perforce Server using the PerfMerge++ tool. The Import Mode is considered to be the safest method as all files are imported through a Perforce Client. Convert Mode is significantly faster, but requires an understanding of Perforce database administration.

Convert Mode is an advanced feature and should only be attempted by a Perforce expert familiar with replaying and upgrading databases. Incremental conversions are not supported using Convert Mode; however Import Mode can be used after a Convert Mode conversion to update the migration.
