You must upgrade through several versions if you do not want to break your data completely.
I would take 5.0 -> 5.2 -> 6.0 -> 6.4 -> 7.0 -> 7.13 -> 8.13 (if that's still the target by the time you've gone through all of tests)
Some of these may be skipped for mid-range or higher versions, but if you're going to do that, please make sure you test test test.
For example, you may be able to go from 5.2 to 6.3 to 7.0, or possibly even 5.0 to 6.3 to 7.0. But you are likely to be in a world of pain if you try to go from 6.2 or lower to 7.0
You must not skip 6.3 or 6.4 to 7.0. If you do, you will find certain stuff stops working in 7.8ish and above. I would also not try to go from anything lower than 7.9 to 8.anything.
Thank you so much for quick response!!
