To upgrade the MikroTik RouterOS from version 6 to 7, there are two methods: using the Winbox upgrade option or manuall upgrade with the RouterOS file and using CLI.
Upgrading from router os version 6 to 7 is a major change, not a simple update. It modifies system configuration and files, which may affect existing configurations and disrupt your services.
So before starting the upgrade, if you have any important configuration in your MikroTik, it is highly recommended to take a backup of your MikroTik configuration. This can ensure you have a restore point that enables you to restore your previous configurations.
In this method, you can use the Winbox application to upgrade RouterOS, which is the easiest approach. However, this method may not always upgrade your RouterOS to the latest available version.
After completing the upgrade, you need to update your MikroTik RouterOS again to ensure you are running the latest version because the MikroTik option of upgrading RouterOS doesn’t update v7 to the latest release.
After logging in with Winbox to your MikroTik VPS, in the left sidebar, click on System and then click on Packages to open the Packages menu.
1. Click System
2. Choose Packages

It’s an automatic option for upgrading and updating MikroTik using Winbox, it first downloads, then installs the updates.
To upgrade in the package list, click Check for Update:

Here you will see the newer versions available for you to upgrade.
It will automatically download the new NPK file, upgrade RouterOS, reboot the device, and then remove the downloaded NPK file after the upgrade.
Switch the channel to upgrade and click on Download&Install:

To manually upgrade your RouterOS to any specific version, you need to download the MikroTik RouterOS .npk file from the MikroTik web page and upload it manually to your router and upgrade it using this file.
This is an advanced method, but you can upgrade to the latest release of v7 on MikroTik by this method.
To download the compatible RouterOS version for your MikroTik. First, you need to check your CPU architecture. Also, make sure you have enough space for the .npk file.
Go to System > Resources > scroll down, then check your CPU architecture and RouterOS version:

You have to download the .npk file from the MikroTik official website with a version that is compatible with your router specifications.
1. Select the architecture depending on what architecture you have.
2. Select the channel. You have three channels to download the MikroTik NPK package:
3. Select the version you want to download and upgrade your RouterOS to:

In this step, you need to upload the downloaded NPK file to your MikroTik files. You can upload your file by easily dragging and dropping it in Winbox or follow the steps below:
1. Click on Files in the Winbox left sidebar
2. Click on Upload and select the .npk file

After the file is uploaded, you should see it in Files.
Verify that the file was successfully uploaded to MikroTik Files by seeing it in Files:

In this step, after uploading your downloaded file, you need to reboot your router. It will automatically upgrade it using the uploaded file, then remove the .npk file.
Click on System > Reboot

You will be asked if you want to reboot your system. Click Yes to reboot.

You can use the MikroTik Terminal instead of the Winbox options for any reason, like remote administration, automation, scripting, troubleshooting, and managing multiple routers. There are two methods using CLI: use FTP and SSH, or Winbox and File in Winbox.
Because MikroTik v6 uses old encryption methods for SSH, new machines and OS don’t accept those encryption methods, so the connection would not be established; you have to use Winbox Terminal instead or the MikroTik OS own console.
You can use MikroTik’s built-in upgrade option, which doesn’t always upgrade to the latest version. After upgrading from RouterOS v6 to version 7, you need to update your MikroTik firmware again
If you are using the Winbox terminal, open a new terminal, or if you are using RouterOS’s own terminal, just run the commands.
system package update install
This command will show you the available version and automatically start to download and upgrade your OS.

To put files in MikroTik without using the graphical interface, you need to use ftp or SFTP. In v6, you can use SFTP because of SSH encryption issues, so you can use only ftp.
First, check whether FTP is enabled in your MikroTik or not.
/ip service print
This will show the services with their ports and names. You can see here that our FTP is disabled.

Use the command below to enable the ftp service in MikroTik:
ip service enable ftp
You can connect to your MikroTik with FTP using CMD or using the FileZilla application, which has a graphical interface and is easier to use.
Enter your MikroTik credentials, enter 21 for the port, and click on Quick Connect.
Drag and drop your downloaded upgrade npk file to the / (root) directory of your MikroTik:

You need to reboot your router. It will automatically upgrade it using the uploaded file, then remove the .npk file.
system reboot
You will be prompted: Are you sure you want to reboot? Type Y and press Enter to reboot your router.
After upgrading, you need to verify whether your RouterOS is upgraded or not. The version must be v7, depends on the method that you used, it might be the latest release or not.
To verify the RouterOS upgrade via Winbox, use the following steps:
First, go to Systems in the left toolbar, then choose Resources.
Scroll down to see the Version section:

As mentioned before, the RouterOS v6 SSH connection can’t be established because of the older method of encryption, but RouterOS v7 uses new SSH encryption, so you can connect to MikroTik using SSH on RouterOS v7.
After you upgrade your MikroTik, you have to verify the upgrade using CLI by following the command:
system resource print

Updating MikroTik RouterOS is like any other system to keep your router secure and working properly. Updates fix bugs, improve performance, patch security problems, and add new features.
