 h3. Slow migration on upgrade
 
 Important!  This upgrade includes a database schema update changing the integer id column in each table from 32-bit to 64-bit.  Because it touches every row in the table, on moderate to large sized installations this may be very slow (on the order of hours). Plan for the arvados-api-server package upgrade to take longer than usual.
