Automated File Migration from AWS to Azure Ubuntu Server? | A Stepwise Guidance

Let’s interpret the process of migrating files and folders from an AWS Ubuntu server to an Azure Ubuntu server along with the necessary code. Files and folder migration in-between different cloud platforms, such as AWS and Azure is a tedious process.

Furthermore, performing migrating tasks manually including zipping, copying, and unzipping files operation takes days or even weeks, depending on the size of the data. However, with a little scripting, we have made this migration process automated and more efficient.

Let’s move gradually—

Pre-Requisites for Migration:

• Your Source and destination servers must have enough disk space to create, copy, and move zip files as well as folders.
• Ensure that you have sufficient permissions to access and modify the files and folders on both servers including source and destination.
• You need to establish an SSH connection in-between source server and destination servers by generating an RSA key pair and configuring authorized keys.

The step-by-step configuration to migrate from AWS to Azure

You need to follow all the mentioned steps to configure your Amazon Web Services to Microsoft Azure migration operation. Let’s initiate!

Step 1:

First, you have to generate an RSA Key Pair on the Source Server Open a terminal on the source AWS Ubuntu server and run the following command to generate an RSA key pair:

ssh-keygen

This command will generate two files: one is a private key (e.g., id_rsa) and another a public key (e.g., id_rsa.pub).

Step 2:

Next, you need to configure authorized Keys on the Destination Server, copy the contents of the id_rsa.pub file from the source server, and finally append it to the authorized_keys file on the destination Azure Ubuntu server.

Basically, this file is located at /root/.ssh/authorized_keys. However, if the file doesn’t exist there, you have to create it.

Step 3:

Now, you have to copy the zipping as well as unzipping scripts of the respective servers such as copy the first.sh script of the source AWS Ubuntu server and then the second.sh script of the destination Azure Ubuntu server.

first.sh script:-> source.sh

#!/bin/bash


# Source folder where the folders to be zipped are located
source_folder="/web/html"


# Destination folder where the zipped folders will be moved
dest_folder="/web/html_moved/"


# Remote server details
remote_server="root@172.208.54.99"
remote_dest_path="/web/html"


# Function to zip and move a folder
zip_and_move_folder() {
    folder_name="$1"
    zip_file="${folder_name}.zip"


    # Print the folder being zipped
    echo "Zipping folder: $folder_name ,command->    zip -r "${zip_file}" "${folder_name}""


    # Zip the folder
    zip -r "${zip_file}" "${folder_name}"


    # Print the zipped file name
    echo "Zipped file: $zip_file"


    # Move the zipped folder to the destination folder
    mv "${folder_name}" "${dest_folder}"


    # Copy the zipped folder to the remote server
    echo "Copying $zip_file to $remote_server:$remote_dest_path"
    scp -r -i ~/.ssh/rsa1 "${zip_file}" "${remote_server}:${remote_dest_path}"


    # Remove the zipped folder from the local machine
    echo "REMOVING $zip_file "
    rm "${zip_file}"
}


copy_file_to_remote() {
    file_name="$1"


    # Copy the file to the remote server
    echo "Copying $file_name to $remote_server:$remote_dest_path"
    scp -r -i ~/.ssh/rsa1 "${file_name}" "${remote_server}:${remote_dest_path}"


    # Move the file to the destination folder
    mv "${file_name}" "${dest_folder}"
}


# Traverse the source folder and zip/move each folder
for folder in "${source_folder}"/*; do
    if [ -d "$folder" ]; then
        zip_and_move_folder "$(basename "$folder")"
    elif [ -f "$folder" ]; then
        copy_file_to_remote "$(basename "$folder")"
    fi
done

This script will assist you in zipping the files and the folders in a specified source folder and then copying those zip files to the destination server. At last, moves the original folders and files to a specified destination folder on the source server.

second.sh script:

#!/bin/bash
# Folder to scan for zip files 
scan_folder="/web/html" 
# Destination folder for moved zip files 
dest_folder="/web/zip_moved/" 
# Function to unzip and move a zip file 
unzip_and_move() { local zip_file="$1" 
# Unzip the file 
unzip "$zip_file" 
# Move the zip file to the destination folder
 mv "$zip_file" "$dest_folder" } 
# Traverse the scan folder and unzip/move each zip file
 for zip_file in "$scan_folder"/*.zip; do if [ -f "$zip_file" ]; then unzip_and_move "$zip_file" fi done

You can use this script to unzip the copied zip files on the destination server and move them to a specified destination folder as well.

Step 4:

From here, you can run the scripts on the source AWS Ubuntu server, and navigate them to the directory containing the first.sh script and lastly run the following command:

sh first.sh

Additionally, with the help of this code, you can initiate the zipping and copying process.

For this, this script will scan the specified source folder and will zip each folder and file individually. Later, will copy the zip files to the destination server, and move the original folders and files to the specified destination folder on the source server.

Once the first.sh script has been completed, you have to log in to the destination Azure Ubuntu server and navigate to the directory containing the second.sh script.

And finally, run the following command:

sh second.sh

By carrying this script, you can unzip the copied zip files and move them to the specified destination folder on the destination server.
