The process of copying or moving important data to another server and configuring the new server to take its position as the primary server is known as server migration. Server migrations in the context of online hosting could involve setting up the web server and database software and transferring websites and their configurations. It also refersto altering DNS settings to point users to the new destination server. Many web hosting companies like Oxtrys provides server migration for their clients as per their needs.
Normally, a server migration takes between 30 minutes and three hours. This is because the amount of data that needs to be moved will greatly affect how long it takes to migrate servers. To facilitate jobs like these, servers only have a given amount of bandwidth. The migration procedure will use more of the server’s bandwidth as you raise the number of files and programs being moved. Because of this, the process ultimately takes longer.Dedicated servers are more less expected for migration due to their dedicated resources.
Need for server migration
A server relocation may be required in some potential circumstances. Companies may migrate to:
- Benefit from new technology or improved services, or make sure that the hardware and operating system (OS) that the new technology depends on remain up to date.
- For more flexibility or scalability, move to the cloud.
- To centralize and save money on hosting, therefore lowering CapEx.
- At the end of its useful life, replace old infrastructure.
- To achieve high availability and reduce demand at a single location, hosting should be expanded and distributed.
Steps to follow for a server migration plan
A successful server migration involves several stages. The multiple processes required to migrate servers often fall into five main categories, which together make up the whole migration process.
Creating your precise plan in the future requires an understanding of how these more general server migration processes go together and what is contained in each. The following are the actions to take for migration:
The Setting Up of Your New Server: Your new server must have enough space to accommodate all of the data related to your website and applications. Because of this, it is critical to make sure your new server is suitable in terms of capacity and configuration for any incoming data and digital assets. Additionally, it is crucial to confirm the installation and accessibility of the mission-critical services and software packages that your sites rely on in the new environment.
Analyze the fidelity of the data: Before the migration, it is crucial to follow a process to ensure that all data has been accounted for. One CSS file or connection string lost in transit, for example, can have a significant impact on the performance of your entire website or application. It is advised to take some time before migration to identify the essential components of your site and the areas that connect with other services.
Transfer of Data: The most time-consuming aspect of relocation is often data transfer. You are now finally prepared to begin the transfer after setting up your new server and adequately securing all data.Essentially, the migration is carried out through the available bandwidth between your old and new servers. To move data quickly and with the least amount of downtime possible, you will need additional bandwidth.
Evaluation (QA/QC): The last item on the server migration checklist is just as crucial as any other: describing how you will conduct testing after the migration. Even though it may take some time and effort, making sure everything works well and that all the data has been transferred is time well spent because doing so will help you avoid finding a problem much later. Assuring quality assurance, quality control, and process improvement from one migration to the next requires accurate testing and analysis.
“Going Live” after a DNS change: It is time to change your DNS after you have moved all of your files, programs, and websites to your new server and given everything a thorough test run. As it routes traffic away from the outdated server and toward the new system, this transition is crucial.
It is a fairly easy operation to point your server at a different DNS. Although the procedures are simple, getting them wrong could harm the functionality of your website. You should switch your DNS during times when usage is not at its peak. Usually, weekends or holidays, middle of the night, are the finest times.
