I did seem to find the info on upgrading with miles (the two sets of upgradable coach fares and the cost in miles) but nothing specific to Evouchers for Senators and what coach fares you can upgrade to business class with.
thanks,
You can upgrade any class (subject to availability

) except S and W on longhaul flights. This is valid for LH and UA operated flights (you must book the code of the operating carrier).
LH upgrades are confirmable in advance, while for UA you have to request a paper voucher, which you take to the airport on the day. UA only upgrade on a standby basis (i.e. you only get the upgrade at the airport on the day of the flight).
As you probably know, you need 1 voucher to upgrade a European flight, or 2 vouchers to upgrade a long haul flight. All vouchers cover 1 flight only (i.e. they will not cover connecting flights except for certain domestic flights within Germany).
