AWS Migration Checklist: Things to Check on Your New Server After Moving Away from AWS

Moving away from AWS is a big step. Whether the reason was rising bills, unpredictable pricing, or the need for more control over your infrastructure, the migration itself is only half the job. This AWS migration checklist after migration covers what to verify on your new server, from data integrity to security, backups, and cost.

A] First, Confirm That Everything Has Migrated Correctly

Despite AWS’s comprehensive cloud services, migrating away from it is not easy. Somehow, if you managed to migrate the data, don’t think you are done. Check the listed things before taking a sigh of relief:

• Application and Website Functionality: Check that websites, applications, web portals, and business software are shifted to the new server as-is and are working as before (normally).
• Data Verification: Ensure each bit of data is moved to the new server. To check, you can run cryptographic hashes or file checksums on the source and target datasets to confirm bit-level accuracy.
• User Access: Verifying user access means checking permissions, verifying security roles, and ensuring access control lists (ACLs) are correctly mapped and functional on the new destination server.
• DNS and Domain Configuration: Verify and update your domain’s DNS records so that web traffic, emails, and other services are pointed to the new server’s IP address.

B] Check the New Cloud Server Performance After Migration

One of the primary post-AWS migration checklist items is checking the new server performance, as without it, the server is useless. Right?

A high-performance server has standout performance features, and they show up upfront. The features usually include:

• Dedicated Resources: High-performance servers always offer their tenants dedicated computing resources. The user has the sole right to use all of the server’s resources including CPU, storage, RAM, etc. If your new cloud provider is offering the same, you are in the right place.
• Predictable Speed: The new server you migrated to should have predictable speed (high), as it is one of the top factors that can affect your website reputation as well as ranking.
• High I/O: High I/O (data input/output) loads the pages swiftly and returns the query to the destination server very fast. Not only that, but high I/O does more than that. So, check your server’s data input/output speed.
• Stable Network Latency: Low and stable network latency is a required feature of high-performance servers. If the new server you are hosted on has extremely low latency, you will be worry-free about loading speed.

Absolute Cloud, a well-regarded cloud service provider in India, offers specialised dedicated cloud servers that are built for performance. Each server contains every performance feature, including dedicated resources, predictable speed, high I/O, and extremely low network latency for enterprises of every size.

C] Review Security After Moving From AWS

AWS provides you with a long list of built-in security tools, such as IAM, security groups, GuardDuty, and CloudTrail. Once you leave, none of those protections come along automatically. Your new server needs its own security layer, and you should verify it from day one.

• Firewall Rules: Confirm that only the required ports are open. Replace AWS security group rules with equivalent firewall policies (inbound and outbound) on the new server.
• SSL/TLS Certificates: Reinstall and validate certificates for all domains, and check that HTTPS redirects work correctly.
• Access Control: Disable unused accounts, enforce strong passwords or key-based SSH authentication, and enable multi-factor authentication wherever possible.
• Patching and Updates: Make sure the operating system, control panel, and all applications are fully updated.
• Intrusion and Malware Protection: Set up monitoring, log auditing, and DDoS protection to catch threats early.
• Compliance: If your business follows standards such as ISO, GDPR, or industry-specific regulations, confirm that the new environment still meets them.

How Absolute Cloud helps: On AWS, security follows a shared responsibility model, and much of the configuration burden falls on your team. With Absolute Cloud, security hardening, firewall configuration, and proactive monitoring are handled by an in-house team that knows your setup, so you are not left decoding complex policy documents on your own.

D] Check Your Backup and Disaster Recovery Setup

Many businesses relied on AWS services such as S3, EBS snapshots, or AWS Backup without giving them much thought. After migration, those safety nets are gone, and an unprotected server is a serious risk.

• Automated Backups: Confirm that scheduled backups (daily, weekly, or as your business needs) are running successfully.
• Backup Storage Location: Backups should be stored separately from the primary server, ideally in a different location.
• Restore Testing: A backup is only useful if it restores properly. Run a test restoration and check the results.
• Retention Policy: Decide how long backups are kept, and make sure it matches your business and compliance requirements.
• Disaster Recovery Plan: Define your recovery time objective (RTO) and recovery point objective (RPO), and document the steps to follow if the server fails.

Absolute Cloud builds its infrastructure on a resilient, fault-tolerant design. Combined with regular backups and redundancy, it keeps your data protected and your downtime minimal, without the add-on backup charges that often pile up on AWS.

E] Review Your New Dedicated Server’s Cost Structure

One of the biggest reasons businesses leave AWS is cost. AWS bills are notoriously hard to predict because of layered charges for compute, storage, data transfer (egress), IOPS, load balancers, snapshots, and support plans. After migration, confirm that your costs are actually lower and clearer.

• Compare Actual Bills: Put your last three months of AWS invoices next to your new server’s bill.
• Check for Hidden Charges: Look for extra fees on bandwidth, backups, IP addresses, monitoring, or support.
• Right-Size Resources: Make sure you are not over-provisioned. Pay only for the CPU, RAM, and storage you use.
• Review Contract Terms: Understand billing cycles, renewal terms, and upgrade costs.

The Absolute Cloud advantage: Absolute Cloud offers transparent, fixed pricing on dedicated cloud servers. There is no surprise billing and no complicated usage-based metering, so you know your monthly cost in advance. For growing businesses, this predictability makes budgeting far simpler than anything AWS offers.

F] Don’t Forget to Clean Up Your Old AWS Environment

Leaving AWS resources running after migration means paying for infrastructure you no longer use. Once you have confirmed the new server is stable, work through this cleanup:

1. Take a Final Backup: Before deleting anything, keep a complete archive of your data and configuration.
2. Terminate Idle Resources: Shut down EC2 instances, RDS databases, load balancers, and Elastic IPs.
3. Delete Storage: Remove unused S3 buckets, EBS volumes, and old snapshots.
4. Revoke Credentials: Delete access keys, IAM users, and roles tied to the old environment.
5. Check Billing: Monitor your next AWS invoice to confirm all charges have stopped.

Unused resources are a common reason for unexpected AWS bills after a migration, so do not skip this step.

AWS follows a variable pricing model, so leftover resources or usage above your limit can show up as surprise charges, while Absolute Cloud’s fixed pricing means you pay only for the CPU, RAM, and storage in your plan. Extra bandwidth, dedicated support, and backups are billed separately on AWS, but Absolute Cloud includes unmetered bandwidth, daily backups, and dedicated support in one all-inclusive plan. Once your old AWS environment is shut down, you get a predictable monthly bill backed by 24/7 support with a five-minute response guarantee.

G] Monitor and Optimise the New Dedicated Server

The first few weeks after migration are the best time to catch issues. Set up monitoring so you can act before users notice a problem.

1. Resource Monitoring: Track CPU, RAM, disk usage, and network traffic.
2. Uptime Monitoring: Use alerts to be notified immediately if a website or service goes down.
3. Performance Tuning: Optimise databases, caching, and web server settings based on real traffic.
4. Log Reviews: Check error and access logs regularly for unusual activity.
5. Capacity Planning: Watch growth trends so you can scale before resources run short.

With Absolute Cloud, monitoring is not something you have to build from scratch. Proactive monitoring and expert tuning are part of the service, so your team can focus on the business instead of the infrastructure.
