[support] 4.6.4 > 4.6.9 upgrade path

[pault]

hi all

i have had to revert a test site to a 4.6.4 back up version. it has 
some patches applied so doesn't operate on our main drupal install.

i obviously want to get this up to 4.6.9 asap. is it ok to go 4.6.4 > 
4.6.9 or do i have to go 4.6.4>.5>.6>.7>.8>.9? i am familiar with the 
untar, do diffs etc malarkey, just want to know if i can get away with 
doing it once rather than five times.
