Rackware – Workload Migration (RMM) – Part 1

Migrating application and database servers from on-prem to cloud is really challenging. Current era organizations are focusing to stretch towards clouds to optimize their workloads.  This gives immense pressure on IT architects and administrators on how swiftly and smoothly they can migrate servers to the cloud.  

After the migration, the next challenge is to have an optimal DR strategy. The best practice would be replicating the servers to different regions.  There are many tools in the market to address these challenges,  

RMM is a great tool to address migrations and DR strategies.

Product Overview

RackWare Migration Manager (RMM) is a third-party application that we employ as a Cloud Migration and Disaster Recovery solution. RMM is compatible with all of the major cloud providers including Oracle, Azure, AWS, and Google Cloud, and can also be used in On-premise scenarios.

The product consists of following areas :

  1. Discovery and Analysis
  2. Workload Migration
  3. Disaster Recovery and Backup
When organizations are planning to move their current VMware, Hyper-V, or Oracle VM to the cloud, RackWare is a really good solution to cater to this environment. This migration methodology in addressing migration at the VM level.

2. Setup network ingress and egress rules allowing communication between source and target networks.

3. Initialize and license the RMM Server then start the RMM service.

4. Configuring SSH connectivity between source and the target server.

5. Create Cloud User and Policies

6. Create and configure a ‘Wave’ within the RackWare Admin UI. 

Note: If we are planning to use the same IP Address Subnets on the source and target networks we will require a bridge network.
