How to launch a second advanced application on Shopify Marketplace?

[GemFind]

Hello Team,

Thanks for your all kind support and help to make our business more active. 

At present, our 5 apps are available on Shopify Marketplace to serve our clients. Also, more are in progress and we will submit them soon to the Shopify support team for the approval process. 

However, we are developing our Ring Builder app with new technology and a few additional features that are frequently asked by our existing and new customers. But, the application is already listed on an older platform - https://apps.shopify.com/gemfind-ring-builder

Now, we expect to launch the advanced application either under the same roof or under the name RB Advance Tool. So, we require your guidance on how can launch our 2nd application. 

Previously, we think about providing a facility to upgrade the application within the same scope but it is very difficult because of platform and technology changes. The existing application has been built in core PHP with native features whereas, the new application we are building in React+Dot Net API endpoints for a faster response which is totally different from the application platforms. Perhaps, we will require the existing application active even if the new application gets up because of use by our existing clients. We can't get the application down suddenly because huge clients are using the application. 

Therefore, kindly guide us to resolve the problem and to make our advance application approved by the support team.

Let us know if you need any further information. 

Have a nice time ahead.

Thank you.
