@espoem,
The previous post is for step-by-step procedure on how to setup a witness server (for first time install).
This is a complete guide on how to Migrate witness server from OLD to NEW upgrade, there are some critical steps to follow for the Witness not to miss a block, properly disabling key, shutting down the node, etc.
I updated the link and removed the steemit tag.
Thank you.
Approved.
