Syslog 2.0 Requires an Entire Reinstall.Please uninstall Syslog and Remove all Data before Installing.Migration is possible, but you must plan this in advance.No automatic migration is supported.
When you have very large tables, performing a Truncate will be much quicker.If you are concerned about archive data, you can choose either Inline, which will freeze your browser for the period of this upgrade, or background, which will create a background process to bring your old syslog data from a backup table to the new syslog format.Again this process can take several hours.
