NZDM query

We are planning to migrate from ECC5 to ERP6 EHP6. ECC5 was on sql 2005 so we migrated it to SQL 2008 however we are still not eligible for compression because of being on unsupported/lower Basis SP level

So we now have ECC5 on SQL 2008 and planning a release upgrade. Is NZDM still a value proposition given our ECC5 data is in 2008 r2 format but uncompressed. I know there is no direct relation but just checking if NZDM was only tested on compressed PAGE compressed data format or the use case applies to us also. Please share your experience or thoughts. Thanks for reading

    Hi Kalyan,

    the NZDMs Record&Replay technique's advantages are independent from the data compression settings of the database.

    Your product and database version is supported without restrictions (see note

    1678565 - Prerequisites, Terms and Conditions for nZDM/SUM)

    If shortening the upgrade downtime is an important KPI in your project, nZDM is a good option.

    (See more details in the blog

    Best regards,
