An ADC Version Migration Tool Checklist: 4 Capabilities for Success


Applications act as a consumer gateway for banking, financial services, entertainment, healthcare, and other businesses. Application delivery has changed along with the challenges that IT faces. To meet IT needs and address growing business demands, ADC vendors release new versions with technology advancements. While enterprises recognize the benefits of version migration, there are significant challenges that are involved in upgrading an ADC to its latest version. Each ADC may be handling multiple applications owned by different business units with distinct priorities. To ensure successful version migration and minimize application downtime, you need to have the right planning and migration technology in place. Here is a checklist of four capabilities to look for in a version migration tool.

1. Automation

Upgrading ADCs with the traditional, manual approach is not only cumbersome but also prone to errors and delays. Migrations can either be box-level or specific object-level. An effective migration tool must be able to track object-level dependency mapping and automate the implementation process to address various scenarios. Using these capabilities can decrease the time, effort, and cost of migrating versus using manual processes and/or scripting.

2. Flexible workflows

ADC version migration requirements differ for different application teams and organizations. Your migration tool should be aligned with the enterprise’s change methodology and any ITSM systems that are used to manage infrastructure changes. Integration with these ticket systems provides centralized workflow management and automation of version migration requests.

3. Pre-validation and post-validation checks

Each organization follows its own set of standards to deploy an application. When multiple objects are involved in the migration, tracking with spreadsheets is inefficient. The IP addresses of the migrated ADC objects may conflict with existing application ADC objects, and if not resolved, will lead to application unavailability. Your migration tool should provide all necessary checks before and after migration, ensuring that only error-free configurations are migrated. In the case of contingency, it should have a provision to roll back the changes gracefully.

4. On-premises and cloud management

Enterprises are migrating their workloads to the cloud, which offers more flexibility and on-demand resources to handle dynamic peak loads. An effective migration tool should enable you to manage and upgrade on-premises and cloud environments. Even if you haven’t defined your cloud adoption strategy, having a tool that manages cloud and on-premises environments is an added advantage for embracing cloud.
