Use cache dir in different server

[Landy Landy <landysaccount@xxxxxxxxx>]

Hello. Happy new year to all.

I am replacing a server I currently have with squid 3.0.20 to another box with a bigger hard drive. Right now I have about 40GB of cache that would like to move to the new server. My question is: can I just copy /var/log/squid/cache ( cache_dir aufs /var/log/squid/cache 40000 64 255
 ) to a different hard drive?

and

if the new hard drive's config is: cache_dir aufs /var/log/squid/cache 100000 64 255. This one 100GB for cache. 

Would I have problems putting the 40GB cache on to the 100GB?

Thanks in advanced for your help.
