Results

The monitoring screen appears, where you can view the log of all tasks involved in the process.

The process will stop twice to perform the following manual activities in the nZDM UI:

  1. To record the data on the source system, perform the following manual activities:

    • Configure the nZDM recorder

    • Start the recording

    The SAP Landscape Management software creates a clone and fences the cloned system off from the remaining network.

  2. To replicate all changes that have been recorded on the source system to the target system, perform the following manual activities:

    • Start the replication on the target system

    • Finish the nZDM procedure

SAP Landscape Management finally promotes the cloned system to become the new productive system.
