Migration Lab Setup

• Since we don’t have on-premises we will be simulating the on-premise
• To Simulate On-premise
• Database:
  • We will create a VM in any cloud (AWS/Azure)
  • Install Database Management System
  • Import some sample data into database
  • Now we will setup the migration to AWS using Database Migration Service where our target will be AWS Relational Database Services (RDS)
  • Scenarios:
  • mysql to AWS RDS
  • postgreSQL to AWS RDS
  • Source:
  • Any VM in AWS/Azure
  • Destination
  • AWS RDS
• Server Migrations:
  • We will be create a VM in Azure with Windows Server 2016 and Hyper-V as hypervisor
  • Using Hyper-V we will create two virtual machines
  • Our target is to migrate these two virtual machines into AWS
  • Source:
  • Particular VM in Azure
  • Destination:
  • EC2 instance in AWS

Database Migration using AWS Database Migration Service

Source Environment Creation

• In this step we will try to create an EC2 instance where we will install the mysql database and import some data into it.
• mysql by default runs on 3306 port
• Create an Ubuntu 20.04 EC2 instance (Simulated On-premise Database Instance)
  
  
  
  
  
  
  
  
  
• To connect to the ec2 instance ssh -i <path to pemfile> username@ipaddress
• Refer Here for the steps to install mysql on ubuntu 20.04
• After installing the mysql login into mysql shell
  
• Lets create a user for migration => awsmigration
• Now Execute the following commands

create user 'awsmigration'@'localhost' Identified by 'MotherIndia@123';
GRANT ALL PRIVILEGES ON *.* TO 'awsmigration'@'localhost';
exit

• Now login with awsmigration user

mysql -u awsmigration
