This content database has a schema version which is not supported in this farm

we usually face this issue when we try to mount content db.

It is because of the database version conflict.

Just go to your local database and open Versions table and check the version of your database.

now open the database which you are trying to mount and open the Versions table and change its version as per your database version.

now try to mount your database again.

Mount Content DB:

Mount-SPContentDatabase -Name WSS_Content_DB_ToAttach 

-WebApplicationhttp://mywebapplication:port

Dismount Content DB:

Dismount-SPContentDatabase -Identity WSS_Content_DB_ToAttach

Remove Content DB:

Remove-SPContentDatabase -Identity WSS_Content_DB_ToAttach

link button property to open in new tab?

 By Adding following onClientClick even in your link button we can open the url in new tab.

OnClientClick="aspnetForm.target ='_blank';"

so on click it will call Javascript function an will open respective link in News tab.

<asp:LinkButton id="lbnkVidTtile1" OnClientClick="aspnetForm.target ='_blank';" runat="Server" Text="New Tab"  />

and another option is you can go for Hyper link control to achieve this. By default it has the Target property and you can set that to _blank.

thank you,
