Hi all! Today I bring some PowerShelling to change the topology of our farms.
Imagine the following scenario: For several reasons, you had to install in the SharePoint farm all the components in a single server, but after a time your company decides to implement a new server to dedicate the search process on it. Your initial topology would like the following:
But as I said previously, you want to add another server to the farm and then configure this new server to change the search topology, but you want to mantain the existent Search configuration. You will be thinking, what can I do? The answer is pretty simple: PowerShelling 🙂
In the next lines I will post the PowerShell code that I used to change the search topology of a farm. Be aware that you will need to change the names of the variables 🙂

After executing this PowerShell, we have to wait until the server has done all the changes in the search topology, so be patient. After a while you’ll see a screen like the following:
Now you’ll have the search components between the servers.
Happy Powershelling!!
Note 1: If you receive an error related with the index, be aware that is not possible to put the same old index location and the new index location in the same folder. I suggest to create a new folder called “New Index” or something like that
