Important notes

If you want to update from an earlier version, for example, from 5.3.0 -> 6.0.3, follow this path: 5.3.0->5.4.5->6.0.3.

You do not need to go 5.3.0->5.4.0->6.0->6.0.3. That is to say, there is no need to the '0' version. You can just update directly to the minor version, skipping 5.4.0 and going directly to 5.4.5.
