Creating web application from existing content database

There are situations where you want to propagate one SharePoint web application
to some other farm/machine. I feel the fastest way is to take content database backup
and restore it in your destination farm. I have done so in last couple of weeks
and I have leaned how to quickly do that.

Here are quick notes from my experience:

Pre-requisites:

1. I was provided with content database backup and source code. That makes be able
2. to restore site and generate wsps from source code.

Creating content database from backup:

Go to your database server and do following:

1. Create a blank database that will be used as content database Restore a database
2. using content database back up from source farm.

Creating a web application:

1. Go to sharepoint central administration and create a new web application
2. While creating a new web application, use existing content database in database

          section

     3.  Sometimes if your database is too large, web application creation takes too long

          and times out. Don't worry at all. web application is still created successfully.
          It happened to me 4 times out of 5.

Validating the web application:

1. Go to sharepoint central administration, click on application management. In "Databases"

          section you will find "Manage content databases"

     2.  Choose your application and it will show database status and number of site collections.

          If you are not sure how many site collections are there in backup, anything greater
          than 0 is good news.

Configure web application to work properly:
we are almost done now. Do following:

1. Go to sharepoint central administration
2. Click on "Application Management"
3. In "Site Collections" section click on "Change site collection administrators"
4. choose your web application set proper data in site admins.

Additional optional steps:
After performing all the above steps, it is still possible that you are not able
to access your web application.

1. Last thing to do is to install and deploy wsp by using stsadm or your favorite method.

Conclusion:

It is always challenging to move applications from one farm to another. Specially
when they are depending upon other service applications. In spent last two weeks
to learn how to properly do that. I hope this will help you at some point during
your sharepoint Consulting and development.
