Migrating data from one cluster resource to another on SLES10-SP3/OES2-SP3 using MIGGUI.

Need to move about 1.5tb of data from one resource to another. We will be doing main migration during production over X amount of days. Then plan on doing 'changed file' migration right before cutting over.

Regarding the last migration, would I be better off adding a filter date/time or using Sync? Never used Sync before, so not sure how well it works.

Is one more efficient than the other? Will be very interested in time savings on the last cut.

And any rough idea on how long this might take? Very good 1gb network.
