The draw for the six Heineken Cup pools of four teams each will take place on Tuesday, June 8 with the six Tier 1 teams - Munster, Toulouse, Leinster, Leicester Tigers, Cardiff Blues and Biarritz Olympique - kept apart.
And while Racing-Metro 92 and Toulon will take their Heineken Cup bows in round 1 in the autumn, Toulouse will start their defence of a record fourth title by playing their 111th match.
Guy Noves' team added the 2010 crown to the ones they won in 1996, 2003 and 2005 by defeating Biarritz Olympique 21-19 at the Stade de France last Saturday to bring the landmark 15th campaign to a record-breaking end.
The finals of the Heineken Cup and Amlin Challenge Cup tournaments were watched by 127,952 fans - beating the previous best combined mark set in the 2003/04 season by over 32,000 - with 1,081,430 fans going through the turnstiles for the 79 Heineken Cup matches.
Next season's Heineken Cup final will take place over the weekend of May 21-22 at the Millennium Stadium in Cardiff.
