Hi, 

Our organization has hire consultants and they are building a new Citrix environment (we are on older Citrix now). There are a lot of concerns as the project manager is not sure what is the best structure/method to make sure all applications are working properly in the new environment. There are few mission-critical applications such as ERP, POS, etc. I am assigned to work with various user groups and department to structure a testing plan. I wonder if there is any advice for best practices? 

Thanks

ND
