- If you are upgrading from i2 Analyze version 18.104.22.168 or earlier, you must first upgrade your deployment to a supported version before upgrading to this release. The earliest supported version from which to upgrade to this release is 22.214.171.124.
For further information on changes to supported versions, see Configuration and database changes.
- If you are upgrading from i2 Analyze version 126.96.36.199 or later, complete the instructions in Upgrading to i2 Analyze 4.4.0.
If you are upgrading a deployment of i2 Analyze 4.3.3 or earlier that uses SQL Server for the Information Store database, you must install a later version of the ODBC Driver SQL Server and sqlcmd utility. For more information, see Software prerequisites.
As part of the i2 Analyze upgrade process, WebSphere® Liberty, Solr, ZooKeeper, and Java™ are updated. You do not need to download and update these prerequisites before you upgrade an existing deployment.
