Cannot edit column type and set it as URL

Question

I'm using SharePoint 2013. I have a list with custom columns. One column is text type, and I want to set it as URL type. In SharePoint Designer, I can change the type, but I can't choose "URL" type.

I tried in powershell, doesn't work too. According to this site.

$site = Get-SPSite -Identity "http://serverName/"
$web = $site.RootWeb 
$field=$web.Fields["Custom Site Column"]
$field.Type= "URL"
$field.Update($true)
$web.Dispose()
$site.Dispose()

I also tried :

$field.Type= [Microsoft.SharePoint.SPFieldType]::URL

Instead of :

$field.Type= "URL"

But when I did the Update($true) or Update(). Answer an error like : you cannot use this type. I don't want to delete the list and create it again, because there is lots of aspx page inside and else.

Any ideas to force the column type to be URL ?

You can try with Sharepoint Manager 2013. First test with sample column then apply to your column.

You can download sharepoint manager from:
