Claim:
A computer implemented method for migrating a file sequence from one workspace to another, comprising: selecting a file sequence from a first workspace managed by a first workspace management system (WMS), said file sequence comprising an existing base file and a first delta, wherein said first delta comprises one or more changes to be applied to said existing base file; obtaining, from the first WMS, said existing base file; causing a second WMS to create a new file sequence in a second workspace, and to create a new base file in said new file sequence based upon said existing base file; obtaining, from the first WMS, a first revised version of said existing base file, wherein said first revised version is derived by the first WMS by applying said first delta to said existing base file; and causing the second WMS to create a new first delta in said new file sequence, said new first delta comprising one or more changes to be applied by the second WMS to said new base file to transform said new base file into said first revised version of said existing base file, wherein said first delta has a first format, wherein said new first delta has a second format, and wherein said first and second formats are different.
