Let’s change the rental server! We introduce the points to move without trouble

Switching a rental server to a rental server management company different from the current one requires various tasks such as e-mail, web server, and website migration. In the unlikely event of a mistake, it can cause enormous damage to your business, so you must have a solid understanding of the migration procedure and content.This time, I will explain the server relocation work step by step. This is essential knowledge for smooth server relocation, so please refer to it.

1. Server relocation steps

Server relocation is to switch (migrate) the rental server management company you are currently using to a rental server of another company. To ensure a smooth server relocation, we recommend that you understand the steps and make a relocation plan. There are five main steps for server relocation. Prior confirmation, application for the destination server, server environment construction, DNS switching, and finally cancellation of the old server.By performing these steps in an orderly and accurate manner, you can move the server without any trouble. Let’s look at them in order. ◇ Prior confirmation When concluding a server rental contract with the management company of the relocation destination server, it is necessary to consider the “parallel operation period of the old and new servers”. This is the period required to keep emails and websites open during the migration process, so be sure to check when you sign up.

 Application for the relocation destination server

If there is no problem in advance confirmation, proceed with the contract for the relocation destination server.

◇ Building the server environment

After the contract, we will build the server environment, which is a very important step for the smooth operation of the data and services to be migrated. In order to proceed with this step without any trouble, make sure you understand the environment of the mail server and Web server you are currently using, and then set up so that you can use it in the environment of the destination server without any problems. Setup is basically an image of “duplicate the settings of the current server to the destination server”.There are four main items for building an environment, but it depends on the service you are using, so set it according to your own environment.

・ FTP account creation ・ Email account creation ・ File upload ・ Database creation and import

* About website data migration

Of the four items for environment construction, file upload and database import are the most important, so here are some points to consider when migrating.

The points are the following four.

-Keep a backup of the migration source-Select necessary files and unnecessary files properly- Use any tools available- Set backup settings for the migration destination serverBacking up is very important when migrating files because you have to be prepared for accidents such as data loss. In addition, cache files etc. are often unnecessary on new rental servers. You can reduce the number of migration files by sorting properly, so let’s do this when migrating as well.And we recommend that you actively use the tools that can be used for migration. For example, MySQL can be easily migrated without mistakes by using commands such as mysqldump. If you are worried about file migration, you can also use the file migration service provided by the rental server management company.

◇ DNS switching

DNS (Domain Name System) is a system that connects and distributes the IP address of the server (a number such as and the domain. This system runs on the DNS server of a domain registrar or rental server management company.Since the DNS server is set to be distributed to the “source” server before the server is relocated, it is necessary to switch the DNS so that it can be distributed to the “destination” server. However, it takes about 2 to 5 days to switch DNS, so make sure to set a parallel operation period between the current server and the destination server as explained above.

◇ Cancellation of the old server

 Cancellation of the old server is performed after confirming the normal operation of all functions and services on the new server. For example, before the DNS switching work is completed, the old server cannot be stopped because the old server has access to mail and websites. After switching the DNS, all the mails remaining on the old server will be received, and the cancellation procedure will be taken only after the website switching confirmation is completed.

2. Introduction of server relocation service

Relocating a server involves complex tasks as described above. If you are a little worried about the relocation work, why not use the server relocation support of the rental server management company.CPI provides a server transfer support service, which supports the migration of web contents and settings such as email accounts for free. In addition, we can handle all the migration work of running websites, email data, CMS with complicated settings, and Windows Server (for a fee). This service is especially recommended for those who are not sure about the current status of the server or system, or who want to complete the server transfer in a short period of time.


Care must be taken to ensure a smooth server relocation. In addition to the work steps required for server relocation, it is necessary to understand the system status of the current server and application settings, and to reflect them on the relocation destination server. If you are worried about server relocation work or want to complete the relocation in a short period of time, why not consider using the server relocation service?
