We have LEM 5.7 and want to update to LEM 6.0 ... Naturally there is invaluable log data which needs to be preserved in the process.
Are there any issues regarding data preservation/migration when updating?
You will not lose historical data when you upgrade from LEM v5.7 to LEM v6.0. As a best practice, always take a snapshot 'of the VM as a backup before proceeding with the upgrade
