Hi, I built software as website using VS2013 asp.net with sqlserver 2008 R2 and hosted on production server. Also, my customers are using the software for last one year. I usually deploy the new feature build in every month after 7 pm on last Friday of every month. I am planning to do the deployment during office hours(b/w 8 to 6) which should not impact the customers. I wanted to do the deployment and parallely my customers can use the website . I can create separate VD on IIS to have my latest code deployed and tested then i will point it to it when testing is done. Hope no issue will come on Application server side. But how do i maintain my database
because i should not execute the schema changes and other DDl and DML changed on the Production database as it is live and used bu the customers.
What is the best way to achieve this scenario? How do i maintain the transaction?
Do i need to have another database instance and once the deployment over should i need to sink? I don't have any idea as of now how to proceed with this. Any suggestions please how to implement this.
how do i achieve this concept. please suggest me
