Having multiple templates in a single chart

[Ritvik-rc]

I have a helm chart with templates for resources like deployment, service, ingress, HPA etc. The initial chart version is 0.0.1. I have about 15 releases installed using this template in different environments.
I am now making modifications to my templates and adding few conditional statements and making modifications in values that the template is expecting. I am making this as Chart version 0.0.2

I am unable to find a way to use new template (from 0.02) for few of the deployments and continue using the old template (from 0.0.1) for the remaining micro-services. Please suggest a solution for this.
Thanks for your help in advance
