Migrating SharePoint on-prem to SharePoint cloud
Historically a direct upgrade path was only supported from the previous version of the product to the next, but this is only applicable to upgrades between on-premises versions...
When migrating from SharePoint On-premises to SharePoint Online (SharePoint cloud), 3rd party products in general provide the beste experience. ShareGate, Metalogix and AvePoint are big players providing 3rd party migration tools. You should check their websites but there are lots of blogs out there comparing the products.
Microsoft also provides a Migration Tool, I have no experience using it and I actually don't know if SharePoint 2007 is supported
