# Overview
11+
12+
13+
This script allows you to to set or change the license type on all Azure-connected SQL Servers
14+
on a specific resource, in a single resource group, a specific subscription, a list of subscriptions or the entire account. By default, it sets the specified license type value on the servers where it is undefined. But you can request to set it on all servers in the selected scope.
15+
16+
You can specify a single subscription to scan, or provide a list of subscriptions as a .CSV file.
17+
If not specified, all subscriptions your role has access to are scanned.
18+
19+
If the license type is not specified, the value "Paid" is used.
20+
21+
22+
# Required permissions
23+
24+
You must have at least a *Contributor* role in each subscription you modify.
25+
26+
# Launching the script
27+
28+
The script accepts the following command line parameters:
29+
30+
| **Parameter**                                         | **Value**                                                                       | **Description** |
31+
|:--|:--|:--|
32+
|-SubId|subscription_id *or* a file_name|Optional: subscription id or a .csv file with the list of subscriptions<sup>1</sup>|
33+
|-ResourceGroup |resource_group_name|Optional: Limit the scope to a specific resource group|
34+
|-MachineName |machine_name|Optional: Limit the scope to a specific machine|
35+
|-LicenceType | "Paid" (default), "PAYG" or "LicenseOnly"| Specifies the license type value |
36+
|-All|\$True or \$False (default)|Optional: Set the new license type value only if undefined|
37+
38+
<sup>1</sup>You can create a .csv file using the following command and then edit to remove the subscriptions you don't want to scan.
39+
```PowerShell
40+
Get-AzSubscription | Export-Csv .\mysubscriptions.csv -NoTypeInformation
41+
```
42+
## Example 1
43+
44+
The following command will scan all the subscriptions to which the user has access to and set the license type to "PAYG".
45+
46+
```PowerShell
47+
.\update-license-type.ps1 -LicenseType "PAYG" -All
48+
```
49+
50+
## Example 2
51+
52+
The following command will scan the subscription `<sub_id>` and set the license type value to "Paid" on the servers where it is undefined.
53+
54+
```PowerShell
55+
.\update-license-type.ps1 -SubId <sub_id> -LicenseType "Paid"
56+
```
57+
58+
# Running the script using Cloud Shell
59+
60+
Use the following steps to run the script in Cloud Shell.
61+
62+
1. Launch the [Cloud Shell](https://shell.azure.com/). For details, [read more about PowerShell in Cloud Shell](https://aka.ms/pscloudshell/docs).
63+
64+
2. Upload the script to the shell using the following command:
65+
66+
```console
67+
curl https://raw.githubusercontent.com/microsoft/sql-server-samples/master/samples/manage/azure-arc-enabled-sql-server/modify-license-type/modify-license-type.ps1 -o /modify-license-type.ps1
68+
```
69+
70+
3. Run the script.
71+
72+
```console
73+
.//modify-license-type.ps1 -LicenseType "PAYG"
74+
```
75+
76+
> [!NOTE]
77+
> - To paste the commands into the shell, use `Ctrl-Shift-V` on Windows or `Cmd-v` on MacOS.
78+
> - The script will be uploaded directly to the home folder associated with your Cloud Shell session.
