If the new prefix is always longer than the old prefix, increase
the old prefix before replacing it with the new prefix:

lfnfor on
for %%i in (co-*.ext) do ren %%i aa%%i
ren aaco-*.ext 4567-*.ext

If the new prefix can also be smaller the the old prefix, remove
the old prefix before inserting the new prefix:

ren ??-*.ext " -*.ext"
lfnfor on
for %%i in (*.ext) do ren "%%i" %%i
for %%i in (*.ext) do ren %%i 4567%%i

A dos utiltiy, 'COUNT.COM', IIRC, by Horst, mite be useful.
you can increment or decrement any numerical variable.
set SEQUENCE=00
COUNT SEQUENCE
:: increments (the default) by one (the default) variable %SEQUENCE%.
ren FILENAME%SEQUENCE%.EXT NEWNAME%SEQUENCE%.EXT

:: in my batch programs, all batch compiler commands are lower case.
:: all FILENAMES and VARIABLES are uppercase.
