>Topology

The picture below is the topology that will be used for the Downgrade and Upgrade process, namely there is 1 Router, 1 PC and 1 internet. From the router, it is connected to the internet using the ethernet1 port, then from the router using the ethernet2 port which is connected to the PC using the ethernet0 port.

Enter the Router, if there is no [admin@Mikrotik]> display, do this by pressing Ctrl + C and then Ctrl + L. Then create an identity or name for the router by entering the system identity set name= (free name) command. Followed by checking the ip with the ip address print command, as in the picture below the IP appears. Then try pinging using google ip with the command ping 8.8.8.8, if the results are too many, you can stop by pressing Ctrl + C.

>Downgrade

The first step to downrade, enter the system package print command which functions to check the version of the RouterOS system and the packages installed in it. This command is carried out before the downgrade process so that we know the version of the system being used and ensure that all packages are in normal condition. In the image below, it can be seen that the RouterOS version before the downgrade is version 6.46.13. This information is important as a reference to ensure the downgrade process goes according to plan.

Continue by entering the system resource print command which functions to ensure that we know the initial condition of the device, especially the architecture used, in order to adjust the version to be installed later. In the picture below the architecture name is x86_64 which will be downloaded at a later stage.

Then enter the system pack update print command before downgrading, which checks the update status of the packages installed on the system. This command serves to ensure there are no pending updates that need to be applied before the downgrade is performed, and the version is 6.49.13.

To download the achitecture that was previously checked is achitecture x86_64, how to type mikrotik.com in the browser, then enter the tamb software which will appear in the Download Archive section and select the version you want to use for downgrade, here using version 6.49.11, then click the version you want to use.

If you have clicked, scroll down until you find the x86 architecture, select the one with the routeros version and the version that was previously selected and end with npk. The image below will downgrade to routeros version 6.49.11 using architecture x86.

Next click on the router to change the Secondary Console section, namely WinBox, because we will upload the file that has been downloaded at the previous stage in Winbox, if it has been changed click save to save the changes made.

Make sure the device you are using already has the WinBox application, if there is already a WinBox application, enter WinBox then in the Connect To section, enter the IP that was checked at the beginning using the ip address print command. Enter the IP Address in the Connect To section and the login section is filled in with the admin according to the provisions, if so click Connect.

After clicking connect, a display will appear like this, in the left navigation select the Files section and a box will appear in the center as shown below, click upload marked in the image, which serves to upload the file that has been downloaded previously.

If you have pressed the upload section, you will be told to select the file to be uploaded. Select the file to be uploaded, if you have clicked enter then the selected file will appear as in the example image below which has been marked with a red box.

After uploading the downgrade file to the router, use the file print command to check if the file actually exists in the system. This check is important so that we don't make the wrong move when restarting the router to start the downgrade process. That way, we can make sure the file is ready to use, the bar below shows that after entering the print file command, the version we want to use is entered. Followed by entering the system package downgrade command which functions to start the RouterOS downgrade process to a lower version, after the downgrade file (.npk) has been uploaded to the router, and triggers the system to be ready to downgrade to the uploaded version. Then the Router will be Rebooted. Continue?[y/n], select y, because after this command is executed, the router needs to be rebooted so that the downgrade process can take place. Downgrade process completed.

>Upgrade

The first step to upgrade is to enter WinBox according to the previous IP address, then on the left navigation select System and several options will appear, select Packages, to start the upgrade process.

After selecting the packages option, a display will appear as shown below, Click the Check For Updates section marked with a red box, which functions to check if there is a newer version of RouterOS available. This step is important in the upgrade process because it provides information about the latest version that can be installed, so that users can update the system to a newer and more stable version.

Then a display will appear as in the image below, it can be seen that the version being used or the installed version is 6.49.11 and the version we will upgrade as stated in the latest version section is 6.49.18. In the channel section, select stable, which functions to ensure that the router only uses the RouterOS version that has passed testing and is considered the safest and has minimal bugs. If already on the right side there is a Download & Install option, click the option to install or upgrade to version 6.49.18.

The last step to upgrade is, go back to pnet and enter the router terminal. Enter the system package print command, which will bring up the upgrade results, which were previously still in the downgrade version with version 6.49.11 and after being upgraded to version 6.49.18.
