Upgrade and Update Stats

Posted in 2009

We are migrating "in-place" from IDS 9.40FC9W2 to IDS 11.50.FC3. The databases we are migrating are all "up to stats" because we use Art's dostats in a dayly rhythm. In the Migration Guide it is recommended to make an "update statistics medium" on all not-leading index rows. With the databases we are migrating it would last days if we did so. Is it really neccessary to follow that recommandation? Mit freundlichem Gruß Reinhard Habichtsberg Datenbankadministration *-203
