ERROR: Invalid flag in header section of restart file (../read_restart.cpp:857)

I ran a job on a supercomputer with lammps/15082015 and produced a restart file. Now, I want to continue the simulation in another faster supercomputer with lammps/9Dec14.

I get the error:

ERROR: Invalid flag in header section of restart file (…/read_restart.cpp:857)

Is it because of the different versions of lammps? What is the solution for this?
Thanks so much in advance.

yes.

What is the solution for this?

convert the restart to a data file with the native LAMMPS version and
start from the data file instead.
