What is the best way to migrate HP-UX to Azure migration?One of the best ways to migrate HP-UX to Azure cloud is by using the lift-and-shift approach. It is also known as the rehosting strategy. Here the critical workloads like the HP-UX OS and other legacy apps that are running on the outdated PA-RISC hardware are moved to Azure cloud without changing a single line of code.
Charon PAR emulator from Stromasys uses the lift-and-shift migration approach to move the critical applications to the Azure cloud without expensive rewrites, recertifications, or recompiling. This also eliminates any aging hardware dependencies while cutting down on costs. Here HP-UX runs natively on Azure, where Charon PAR creates a virtual PA-RISC hardware environment inside the Azure VM (virtual machine). HPE will end standard support for HP-UX 11i v3 on December 31, 2025. It means there will no longer be any updates or security patches for it. Though it will still get limited support from its vendor. Compared to a full application rewrite, rehosting is a faster, low-risk, and cost-effective alternative for those who want to retain their legacy workloads like HP-UX or are looking for phased migration, as a complete system overhaul can be tricky and expensive and has various challenges that hinder performance and productivity. According to IDC, it costs 2-4 times less than legacy hardware maintenance expenses.
ArticlesThe simplest and most cost-effective alternative to complete migration is to lift and shift your HP-UX application and run it on popular cloud platforms like Azure. This process doesn’t involve any refactoring – therefore, your business-critical applications and processes can run as if they are running on the original hardware. With Charon-PAR, you continue to use the same operating system and applications. Only your current system’s code and data are copied to the new virtual HP-9000 environment.
IMAGINE THIS: you are running your HP UX OS workload on Azure. No more dependency on outdated and risky PA-RISC hardware (HP-9000). No more sky-high maintenance costs. Instead, you have the reliability and scalability of the cloud at your disposal.
Wouldn’t it be great if you could enjoy seamless performance, robust security, and scalability? Your team can focus on innovation without having hardware concerns.
In this article, we will break down the complete procedure. So, without further ado, let’s get started.
Within the next 3 years, 90% of organizations will modernize their legacy applications, with the cloud as the primary enabler. This makes Lift and shift migration on Azure a smart move for any business looking to step into the new era of HP UX cloud computing.
Experience the transformation from a business plagued by frequent system failures to a business at the forefront of future innovation.
Moving the aging hardware from the picture enables you to enjoy absolute peace of mind as system failure and downtime will become a rare phenomenon. Further, the modern Azure infrastructure makes your HP UX OS and workloads run more reliably than ever.
When you migrate HP UX to Azure with lift and shift emulation, you can reduce costs significantly by removing the aging hardware. Additionally, Azure’s scalable platform (with a “pay as you go” model) gives you the flexibility to pay according to your needs.
Forget the headaches of maintaining old hardware! There is no need to look for scarce spare parts, find engineers who know the hardware or pay a higher power consumption bill. Let your business focus on what really matters.
Did you even recognize this? After removing the PA-RISC hardware from the software, the expenses associated with the legacy hardware have been eliminated. As a result, you can now allocate this saved money to other important aspects of your business that have long required your attention.
The seamless process to migrate HP UX to Azure environment makes it easy to move your HP UX OS and applications without changing how they work. Therefore, your legacy applications can still perform mission-critical tasks without the need for costly and time-consuming porting.
With Azure, you get advanced threat detection and top-tier compliance. This way, when you migrate HP UX to Azure, you gain advanced security for your data and applications.
Your data is safe. Azure’s disaster recovery solutions and high availability features keep your operations running, even during unexpected events.
Your business can prepare for future advancements, as there is no need to force your IT team to look backward. When you migrate HP UX to Azure, it prepares your business to adopt cloud innovations easily.
In simple terms, it is the process of lifting your current HP-UX OS and workloads workload from legacy hardware and shifting it to the Azure cloud platform without making any changes to the existing application.
Unlike traditional migration approaches, HP UX cloud hosting with lift and shift ensures your business applications’ functionalities remain unchanged. Best part? Not only does this mitigate the risk of legacy hardware, but it also makes the infrastructure more efficient with Azure.
Imagine moving houses: your old home (HP-UX OS and applications on outdated hardware) has many memories (functionalities) that you cherish. But the building is old and risky to stay in. Now, you’ve decided to move to a new, modern home (Azure cloud platform). The process of moving (Migrate HP UX to Azure) involves packing all your belongings (applications) carefully so they are not damaged (not changing functionalities) and transporting them to your new home, where they will be placed to best use the new space’s advantages (benefits of modern cloud infrastructure).
Just like how moving homes allows you to enjoy a better living environment while keeping your valued possessions…
…this lift-and-shift migration process lets you retain your application functionalities in a more efficient and scalable HP-UX cloud hosting environment.
1. Running Legacy Applications As if It’s Running on The Older Hardware
Instead of rewriting or extensively modifying your HP UX cloud applications, you move them ‘as-it-is’ to Azure. No changes to the application, database and the legacy application. Only the underlying obsolete hardware has been replaced. This minimizes disruption and reduces the complexity of the migration process.
2. Installing Charon-PAR Emulator
The Charon-PAR emulator by Stromasys plays a key role. It mimics the old hardware environment so that when you migrate HP UX to Azure, your applications can run on modern infrastructure without any changes to the software. The emulator software creates a virtual hardware environment so that the legacy software can run as if it’s running on the older hardware.
3. Leveraging Azure’s Infrastructure
Once on Azure, your applications benefit from the cloud’s robust infrastructure. This includes enhanced security, scalability, and high availability – which are not easily achievable with legacy hardware.
4. Maintaining Your Legacy
Unlike application rewriting, with lift and shift emulation, your business operations continue smoothly. Your applications function just as they did before, but now, with the added reliability and performance of Azure’s cloud platform – you enjoy the best of both worlds.
