upgrading from squid 2.6 to 2.7

[Manoj_Rajkarnikar <manoj@xxxxxxxxxxxxx>]

Hi all.

Any special point to note when upgrading from 2.6S19 to 2.7S2. I searched 
for any clues but found none. just tying to confirm. our cache is serving 
~40% of our internet bandwidth and everything would go haywire if it goes 
down during upgrade.

Thanks
Manoj
