How do miners have to upgrade? Does this affect the single miner or also miners working in a pool?
Solo miners, miners using p2pol, and mining pool operators will eventually have to upgrade.

RE: "Is there any web service to see the current ratio of v1 / v2?"

I bet if you ask nicely blockchain.info will create a page. I expect it to take a long time (a year or more) before 95% of the hashing power has upgraded and is producing v2 blocks.

The getblock RPC call will tell you a block's version number; if you're an old bash user like me then you can do something like:
Code:
last=$(./bitcoind getblockcount);
for (( i=last-100; i <= last; i=i+1 )); do echo -n $i; ./bitcoind getblock $(./bitcoind getblockhash $i) | grep version; done
... to see the version numbers of the last 100 blocks (I see 2 of 100 right now).
