Hi @Calvin,
A recommendation is to use:
The “Kothar” app has been the defacto standard in the past, and this new version, despite its beta status is, I believe, the most robust way to copy from one Workspace/Org to another. Note however, that not every single thing is replicated 100% so see the caveats at the site and any warnings during your actual copy which Ditto is good about surfacing.
Hope that helps,
Larry
