Do we need to uninstall old version and delete DB before installing latest version v1.0.0-minus1?
Also, when moving genesis account to new wallet what are the pro tips, do's and don't's - I get the impression from slack that many people have had troubles. Is there a summary of moving genesis steps?
I believe yes, it is advisable to delete the DB files before installing the latest version. Exchange some node IPs in order to have a sound neighbour list and leave it running for the sync. It usually catches up really fast.
The first thing to do, indeed, is to send the whole balance of the genesis account towards a fresh new address, and wait for the 100% persistence.
At first it is possible that you get the "tangle is not solid" error, due to still weak connections. If your neighbour nodes are "healthy", just by leaving your node running for a while will be enough fot a stronger connection, solving the issue (it seems that generating addresses also helps).
Sometimes the transaction from genesis will remain 0% like "forever" (hours without reaching the 100%). The solution I suggest is to create a new transaction (like double spending the first unconfirmed one). In some minutes the second transaction will finally receive the 100% persistence.
I have got three different nodes, and they have been working great.
