How to: Rename a Web Application in SharePoint 2010
Today, I opened up my Central Admin on my test environment, only to be greeted by numerous web applications that I had created in the part in order to work with some project locally.
Their names were in the form: SharePoint + Port Number
I had no clue what was what in there.
I tried to figure out a way to rename my Web Applications but no joy.
After a bit of digging, I came across this wonderful post on sharepoint.stackexchange.com that explains everything wonderfully. A few powershell commands is all it needs. Follow the steps bellow to rename your SharePoint 2010 Web Application from within PowerShell.
$a=Get-SPWebApplication | where {$_.Name -match "Demo"}
$a.Name
$a.Name="New web application name"
$a.Update()
Get-SPWebApplication | where {$_.Name -match "New web application name"}
Thank you Mathieu Chateau.
