Upgrade Tool deleted nodeagents directory when upgrade (reverse order) with multiple domains (6636871)

Description

After a side-by-side upgrade of a configuration that contains multiple domains, only the node agents of the last processed domain are present. This issue occurs because Upgrade Tool removes and re-creates the nodeagents directory in the target each time Upgrade Tool processes a domain.

Solution: To Preserve All Node Agents in a Side-by-Side Upgrade of Multiple Domains

1. After processing each domain, create a zip file of the nodeagents directory.

2. When all domains have been processed, unzip the files that you created.

   All node agents should now be present.
