Is it possible to clone data without stopping the server to replace the HDD with an SSD?

• No installation required
• Online backup per system area
• Transferable to network destination

If you have backup software like this, you may not be able to do anything, but it's not something you can do all of a sudden in the production environment.If you're not good at it, your environment will be ruined.Please stop quietly.

Even if you do it, you will lose any updates you are working on, so it's the same as stopping the service.

If you don't know how long it will take, try a short stop and get a time estimate.

If there are unavoidable circumstances, such as knowing that if you stop, you will never be able to stand up again and save the data, you will have to do so, but if that is the case, I recommend that you pay a company with knowledge and experience it.(It's more like data recovery than migration)

Data migration with RAID disk replacement is out of the question.
