It's uncertain if the software will carry on the content once you upgrade from a version to another major version, but there are two cases:
If the update goes from, let's say 8.0 to 8.1, then the content is kept and it will work normally.
If you upgrade from version 9 to version 10, then it's possible that the software will delete the previous content because many files in new major versions also change.
As an advice, backup the content from version 9 and then upgrade to 10.
