When the time comes to move photos over to another computer (ie say for upgrading machines) would this workflow be ok for transferring photos work so all the metadata/keywords can still be accessed?:

1.export catalogue and save catalogue folder.

2.backup photos from computer (outside of LR) to an external hard drive

3.transfer external hard drive photos onto the new computer

4.Open LR and import catolouge settings

5.All photos should now have their original tags/metadata when you want to export this to another computer?
