Can you get your data out of Zoho if you want later to migrate it to your own dB ?

Can you get your data out of Zoho if you want later to migrate it to your own dB ?

 OK, so you develope your database using Zoho... and later the decision is made to put your own dB online... say with... MySQL, SQL Server, Orcal, or whatever... or migrate to an inhouse dB like the pre-mentioned or MS Access.

Can this be done easily or will it be a large project... or so hard that it wouldn't be worth it...

I'm trying to help someone now who is "trapped" in a product that is no longer supported... they have years of data for their very small business... and thousands of records... a very difficult project.

Thanks for any help.
