  • Migration planning

    • Migration planning reports are not supported for MapR.

    • The following Cloud product/service configurations are not supported:

      • Cloud Product/Service: Azure (IaaS), Azure (HDI)

        Storage Type: Object

        Region: South Africa North, Germany Central, South Africa West, US Gov Iowa, Germany Northeast, US Gov Virginia

    • There is no ability to pick the time for the Cluster Discovery Report (you can pick only the date). The time that gets chosen (automatically) does not match the time (automatically) picked for the Chargeback reports.

      • Is not supported on CDH versions 6.1.1 and 6.0.1. (REPORT-889)

      • Versions of the components shown may be different from those present in the actual source environment. This is because the ones shown are based on the Distribution Stack's Version and not captured from the actual environment itself.

    • Unravel assumes one core on-premises is equivalent to one cloud vCPU and finds the best possible match without taking into account any performance differences. (CUSTOMER-926)

    • The Move to Queue option in Actions (MR APM) does not work. (PLATFORM-1195)

    • Cluster ID missing for MR apps. (PLATFORM-1434)

The exact reason for this bug is yet to be ascertained.
