Hello
I am planning at some stage to upgrade my SP2010 environment which hosts three separate web applications to SP2013. My plan was to upgrade the service databases and then create and upgrade one web application site database and site to SP2013.
Once the first web app site is running fine for a few days I was then going to create a new web app on the SP2013 environment and then import and upgrade the database for the second web application from the SP2010 environment. I was then going to repeat the process for the final web application.
My question is, will creating and upgrading the other two web applications later have any impact on the imported service application databases in the SP2013 environment? Will it have an impact on anything else in the environment?
