After collecting feedback, I am changing those dates to:

Start: Thursday, January 15 at 18:00 UTC
End:   Friday, January 16 at 18:00 UTC

There is some good news however, after some testing it would seem that 
my original estimates for the time to move the filesystem around may 
have been overly conservative and the copy may take less than 12 hours 
all told.  That said, I'm keeping the window to the full planned 24h to 
make allowances for unplanned delays and the possibility that 
performance is lower than expected on the live system.

Thank you all.
