Dexy, you can dig it up with all the usual conditions....as big a rootball as possible, cutting back and have recipient hole prepared and water in well.
however, 10' high and pretty wide?? It will need to be cut back at least by half and will look darn ugly in your new garden. It will sulk for a few weeks too.
I would leave it behind and buy a replacement. It will grow quickly and be a far less time consuming, huffing and panting job
