How to get more than 5000 records using FetchXML query?

Hello,

I need to show more than 5000 record to my Portal website. I am using FetchXML query to get records from my Dynamics 365 instance to Dynamics 365 Portal website. but it can't fetch more than 5000 records in single FetchXML query.

Some article on the web states that it is limitation of FetchXML query. see below :

- http://www.kingswaysoft.com/blog/2013/06/18/Limitations-with-CRM-FetchXML

one of the solution to overcome this problem is to use FetchXML with paging cookie, see here - https://msdn.microsoft.com/en-us/library/gg328046.aspx

but I can not use this as solution as I can't use c# code in Portal website development, is there any way to enhance limit of FetchXML query or any manual way to get record from dynamics 365 instance to dynamics portal?

Thanks,

Ashish
