As you migrate (upgrade) from previous releases of Hyperion Essbase to Release 6, keep in mind that Release 6 of Hyperion Essbase Spreadsheet Add-in is designed to work with Release 6 of Hyperion Essbase OLAP Server. If the Hyperion Essbase system administrator upgrades the Hyperion Essbase server to Release 6, Release 5.x of Hyperion Essbase Spreadsheet Add-in works on only a limited basis. Upgrade to Hyperion Essbase Spreadsheet Add-in to Release 6 as soon as possible.
Read the Hyperion Essbase Start Here booklet and the Hyperion Essbase Installation Guide for detailed information about migrating from previous releases of Hyperion Essbase.
