Following is a summary of what I tried:
---
does anyone knows if it's possible to transfer updated chain files from Windows to Linux?
if yes... what files should be copied?
It is possible...
You want to copy everything except wallet.dat and terracoin.conf. Please, create a backup first!
Thank you for your help! I tried your suggested method, copying everything from Terracoin folder under Windows into Linux .terracoin folder. But, when I try to start terracoind (the daemon) on Linux, I get this error:
"Error: Error initializing wallet database environment /root/.terracoin!"
It seems there is a database incompatibility error... maybe the Windows binaries were compiled with a different database version than my Linux terracoind (compiled from sources, on a machine running ubuntu 10.04 32 bit). So... I am still stucked with an incomplete block database, unable to use the blocks chain from Windows.

Any help or suggestion to solve this problem would be greatly appreciated... Thanks again
