Hi @aldhiblifabrics,
I'm here to share my thoughts and answer your question about company data migration.
There isn't an option to directly export data out of QuickBooks Online from one company to another. Although you can follow the options found on the link I just provided.
For a list of everything you can export out of QuickBooks Online, including the steps on how to do it, refer to this article: Export reports, lists, and more.
Leave your questions or clarifications below in the comments. I'll make sure to get back to you.
