But still preferred to use 1.8 binaries. If anyone is interested and I have time, could try to do the load with 1.9 binaries into 1.8 repository. At the moment I'm loading 1.8 repo into 1.9 one via dump|load. I'll look if starting parallel dump|load would be Ok for hardware, if not I'll start it after this one completes. > You might have a very interesting testcase at hand :-) > > But with such a size repository it might be hard to test different > variants. > > That's true... Well, dump & load from 1.9 to 1.8 took ~14.5 hours so some combinations can be tested. Gert
