Upgrade - Error (check ID 39)

HI all,

Im trying to upgrade a test environment from SAP BO 882 pl 04 to SAP B0 882 pl 06.

After the pre-upgrade check, i get a failed on checkID 39 with description - Change tracking is on, switch change tracking off in "B1 analytic on IMCE 1.0"

It also mentions note 1663948, which isnt released.

Any idea's on how perform this upgrade?
