As a test, I did a rebuild on my 2.50 database, used 3.07 to reimport it to v.3 using the v.2 import feature, and ran v.3. rebuild. After this I ran Statistics Reports in both v.2.50 and v.3.07 and compared them. The results were wildly different in Average Life Span, Life Span Distribution, Number of Marriages, Number of Events, etc. I have 3213 IRN's. Am I doing something wrong? I'm e-mailing the text version of the two reports to Ira. JM
