Prologue

Ace Fekay here again.

You might say to yourself this is some really simple stuff. Sure, it might be, for the pro. As many of you know, I’m an avid Active Directory and Exchange server engineer/architect, and an MVP in Active Directory.

Therefore with AD, Exchange, and Office 365, you will find that scripting comes into play more and more with your daily tasks. The main reason I’m posting simple scripts is that to get the job done, I just needed an arsenal of simple quickie scripts when called upon a simple task, such as this one, when tasked to quickly get a list of users in a group.

I hope this, and my future scripts, especially with Office 365, help you out.

Scope

This is one method to migrate data from one file server to another. I have one method that I will post later, that does it by the share names. This is to just get the two closer to having the same data before I run the final script.

DFS

Keep in mind, we use DFS. I will already have created a new target to the new file server for the current share, but keep the new targets disabled until ready to cut over.

However, when we cut over the target to the new server, we would like to shut off the shares on the source (old) server, to prevent anyone from using it. Of course, we’ve already communicated to the user base the migration schedule.

Therefore, since the shares will be deleted, we must rely on running this by using IP addresses and relative paths from the default administrative shares (c$, d$, etc).

Share and NTFS Permissions Backup

Yes, absolutely! You definitely want to back up your Share and NTFS permissions on this server just in case something happens! The following link is a great article to show you how to do it:

Easy? Nah…

Many may say this is simple stuff. Sure, for the seasoned scripter, which I’m not, The main reason I’m posting this, and I will be posting much more, including Office 365 scripts, is that I had to look it up. I’ve found various websites that provide how-tos, but when it comes to handling variables and piping, I’ve found there is no one place to get various examples and have found myself looking at multiple places to get this info, including my colleagues, who are extremely adept at scripting. With many place, I also see elaborate scripts that do more than what I need. They are fabulous blogs and websites, but sometimes I need the simple one-liners to perform day to day stuff.

Script:

# Uses relative paths
# Make sure you change directory to where your script is located on the computer you are running this before running
#
# =========================================================================================
#Function: Get the Total Size of Folder

function Get-Size
{
param([string]$pth)
“{0:n2}” -f ((gci -path $pth -recurse | measure-object -property length -sum).sum /1mb) + ” mb”
}

cd “C:\PSScripts\OldServerName”

$SourceServerNetBIOSName =     “OldServerName”
$SourceServerIP =         “10.100.200.200”
$DestinationServerName =     “NewFileServer.contoso.com”
