Although that would almost certainly work OK in the OP's case  it would
be safer to use:

's:"\.\./\.\./\.\./arch1/arch14":"../../../../../../foo/foo2/foo3/arch1/arch14":g'

 otherwise if there was  something like "../../d1/arch1/arch14" it would
 become "../../../../../../foo/foo2/foo3/arch1/arch14" which is probably
 not what would be intended.
