Know Your Next Available Options for SQL Database Upgrades & Migration

SQL Server is a RDBMS system that runs several businesses globally and has become an enterprise contender with advanced integration and cloud capabilities. Extended Support for SQL Server 2008 and 2008 R2 will end on July 9, 2019 and several customers will need to either upgrade or migrate their databases.

In Part I of this article series, let us examine the available options for on-premise and cloud services via Azure (IaaS/PaaS), AWS, and GCP. In Part II, we’ll look at the prerequisites for accelerating data loads for SQL Server data to Snowflake!

SQL Server has been the go-to database of choice for both OLTP and OLAP applications over 25 years. According to 2016 data from idatalabs.com, thousands of companies use SQL Server to power their business.

The survey found that in looking at SQL Server customers by industry, Computer Software (14%) and IT & Services (11%) are the largest segments. After 10 plus years in the running, Microsoft is providing customers options on how to deal with their SQL Server 2008 and SQL Server 2008 R2 installations, preferably to the Azure cloud. There are several choices with regards to Azure such as the SQL Database Managed Instance and the on-premises version, SQL Server 2017-2019.

 

An upgrade of SQL Server to the latest version generally translates to higher license fees and cost of operations to prepare and migrate data. However, with cybersecurity attacks, database, and zero-day vulnerabilities on the rise, the cost NOT to upgrade SQL Server is even higher.

  • Security updates: the most stressful risk companies face by running on SQL Server 2008 is lower security. With the end of extended support, no updates will be developed or released. Advanced data security features such as including user-defined server roles, endpoint security, and advanced encryption support to fully safeguard important data will not be available.
  • End of Support: Microsoft will end extended support and technical support/hot security fixes will not be available to businesses.
  • Compliance: organizations will be at an increased risk of failing to meet regulatory standards or industry standards.
  • Operations cost: maintenance costs will increase for aging software and the hardware it runs on. This doesn’t include subsystems such as IDS, firewalls, and networking that’re also required.

The benefits of migrating to the latest SQL Server version are wider data integration options, improved language platform choices, better performance, and advanced security features. There’s certainly a lot more complexity that can be achieved towards Big Data landscapes and Data virtualization in the process. Though the steps of preparing for an on-premise or cloud-based SQL Server upgrade have complexities, it is well worth the preparation. In several cases, the upgrade might be part of a native cloud push or a multiyear cloud migration journey.

SQL Server 2008 Upgrade Prerequisites

Note: SQL Server databases and other objects associated with the previous SQL Server instance must be backed up prior to upgrading.

  • Determine the version of SQL Server for the upgrading: 2017, 2019 or Azure SQL. There’re specific, official Microsoft guides that walk users through a recommended Plan and test the database engine upgrade plan.
  • Be able to run backup and setup operations as an administrator. This step is best left to DBAs and system administrators since there are upgrade options from a remote share as well.
  • Consider the database engine upgrade method guidance workflow as it walks users visually via hardware and integrated services requirements such as SSRS, SSIS, etc. SQL Server 2008 Upgrade

  • Understand the licensing terms for the version of SQL server being upgraded to.
  • The next logical and recommended step is to commence the upgrade using the Installation Wizard.

The above summary list works well in a lift and shift of SQL Server database and will cover database backup and restore procedures.

Upgrade to SQL Server on Azure: extended security updates will be available for free in Azure for 2008 and 2008 R2 versions of SQL Server and Windows Server to help secure workloads for three more years after the end of support deadline. Customers can rehost these workloads to Azure with no application code change using Windows or Linux instances using Azure Portal. Additionally, SQL Server 2008 and 2008 R2 deployments can be moved with no application code change to Azure SQL Database Managed Instance.

Upgrade to SQL Server on AWS: SQL Server on Windows or Linux on Amazon EC2 enables quick to increase or decrease capacity within minutes. Migration of SQL Server databases can be accomplished securely with the AWS Database Migration Service. For SQL Server 2008, databases can be ingested into the AWS cloud and easily upgraded with AWS Systems Manager.

Upgrade to SQL Server on GCP: SQL Server 2008 can run on either Windows or Linux virtual machines using GCP console. There’s wide support for SQL Server from version 2012-2017 and with Express to Enterprise edition support. By the end of the year, CloudSQL for SQL Server will allow customers to migrate existing, on-premises SQL Server workloads to GCP and run them in a fully managed database service that autonomously handles backups, replication, patches, and updates. CloudSQL will preserve existing apps and data while enabling integration with GCP services like BigQuery

Licensing Costs and Updates: if performing an on-premise upgrade, procurement of the appropriate licensing key should be applied. If performing the upgrade on cloud, Azure, AWS, and GCP, license mobility allows BYOL or volume licensing options. With this benefit, customers save up to 55% on the cost of running SQL Server and Windows Server in the cloud. Customers running SQL Server 2008 or 2008 R2 in Azure virtual machines will receive free extended security updates. However, on-premise customers with active Software Assurance or subscription licenses can purchase extended security updates annually for 75% of the full license cost of the latest version of SQL Server or Windows Server.

These initial lift and shift operations on the most common cloud platforms will allow additional time to plan migration activities, including upgrading to newer versions such as SQL Server 2017 and 2019.
