We need to get Sitecore SXA Installed on Sitecore 9.0 Update 2 we are aware that there are 2 ways to do this
1) Using Azure Market place module
2) Using ARM templates
The details are mentioned in this link : https://naveed-ahmad.com/2017/11/05/installing-sitecore-9-on-mircosoft-azure-cloud-as-paas-know-your-options/
But we have already installed Sitecore XP in PAAS and we want install the Sitecore SXA package the way we do in IAAS as mentioned in link.
So questions will we face any issue if we install SXA package in PAAS as we do in IAAS mode
