2. Two possible migrations Of on-prem SQL environment to Azure Cloud
1. IaaS (Infrastructure as a service) OR
2. PaaS (Platform as a service)

3. On-prem SQL environment to Azure Cloud (IaaS Migration)
Migration 1 (Somewhat lengthy)
1. Set-up a new VM on Azure (few mouse clicks)
2. Install your licensed version of SQL
3. Backup/Restore OR Detach/Copy/Attach DB files
4. Transfer database securities (Logins/DB users)
5. Script-out and migrate SQL Agent jobs
6. Modify applications connection string to new Azure VM
7. Migration complete

4. (IaaS Migration) contd…
Migration 2 (Somewhat short)
1. Azure Site Recovery (Preferably work with Infrastructure team)
Replicates on-Prem VM entire content to Azure VM (NOTE: Azure VM name is same but will have different IP Address)
Wait 15mins or so for the new IP address to propagate in your organization network
Preferably failover to Azure VMs and shut on-Prem VMs
2. Migration complete

5. On-prem SQL environment to Azure Cloud (PaaS Migration)
1. Login to Azure portal ( and choose ‘SQL Databases’
2. Set-up a blank database same name as on-prem database
3. Associate the blank database to new 4 parts Server name (mysqlservername1.database.windows.net)

6. (PaaS Migration) contd…
4. Set-up database pricing tier (Database Transaction Units - DTUs based service tier)
Service Tiers – Basic/Standard/Premium
For Example: (Standard S2: 50 DTUs), (Standard S6: 400 DTUs), (Premium P2: 250 DTUs)
Fixed amount of included storage, fixed retention period for backups, and fixed price
All service tiers provide flexibility of changing performance levels without downtime (few mouse clicks)

7. (PaaS Migration) contd…
5. Download the free (Microsoft Data Migration Assistant tool) to on-Prem server or to your laptop
The tool can transfer schema, coded database objects, database security and data from on-Prem database to new blank Azure SQL Database
This tool can also asses and generate report of the on- prem database before migration
5. Modify your applications connection string to point to new Azure SQL Database 4 part server name/database
Repeat Steps 1-5 for each user database
Migration complete
