Getting error Unknown command: `server' on git cvsimport

I followed git-cvsimport documentation to port my legacy code to from CVS to git. Installed cvsps version 2.1 and added to path.

Ran git cvsimport -C <destination_folder> <project_folder_with_cvs>

Getting an error:

Unknown command: `server'

CVS commands are:
    add          Add a new file/directory to the repository
    admin        Administration front end for rcs
.
.
(Specify the --help option for a list of other help options)
Failed to read from server at D:\Git\mingw64/libexec/git-core\git-cvsimport line 420.

I am working in windows 10. Any clue why this error is shown?

Solution

As reported here

git-cvsimport now exits less noisily and prints an appropriate message when the installed cvs binary doesn't know the 'server' subcommand; this happens when cvs is ./configure'ed with --disable-server.

This ticket mentions:

The 'server' command has been replaced with the 'preload' command.

All that is consistent with the git-cvsimport man page:

git cvsimport uses cvsps version 2, which is considered deprecated; it does not work with cvsps version 3 and later.
If you are performing a one-shot import of a CVS repository consider using cvs2git or cvs-fast-export.

Try those latest tools instead.
