There shouldn't be a problem for that. BTW, can you also enter a ticket at Daigrid.org for this matter?

Aw: RE: [gmx-users] Continuing runs from 4.5.4 in 4.6.3
I ran into this, you basically should determine your time frame, and install 4.5.4 if its a problem local (only 1-2 hours), to finish the work, otherwise you need to start from scratch. But I did this with older versions, so do not know about higher versions (such as if theprogrammerseliminated the read version number thing at many of the script initializing things...). The auxillary software does work for analysis, but you end up having to cut things into portions with some aspects, 1/2 one version versus 1/2 the other...but mostly for higher end analysis, not the simplistic ones, such as distance versus hessian matrices or covariance.
