Details for the upgrade path are outlined in the product Release Notes (and several threads in the forums) but there's no reason you can't gor from your current version to 6.x - do make sure you take a backup first.

any documents for steps or help to do upgrade process.

Run the './install.sh' script and it will upgrade your current installation - do make sure you take a backup first.
