From the BOINC/Seti front page:

Tomorrow we are going to start merging the SETI@home classic master science database with SETI@home/BOINC. This will take several days, during which some back-end servers will be offline (splitters and assimilators). We stored up a large queue of work - we are hoping this will keep all BOINC clients occupied during the length of this outage. If we run out of work, we will have to stop the rest of the back-end servers. After we begin the outage, progress will be detailed in Technical News.
