What is IP migration?
IP migration is server migration between locations. These locations may be physical changes in location or change of virtual address. IP migration must be properly managed because the server addresses are not updated over 48 hours in the Internet in some cases. Most IP migration changes are therefore planned for a period of consecutive hours. Others may have to set a specific time frame of the outage in which the migration is to follow. If the company has critical data data that must be moved in the IP migration process, the company can first create a duplicate of such data. Once the data is duplicated, the migration process can use duplicate data for critical missions and move the original data set. After migrating the original data set, the critical process of the mission for the use of the data set is reset rather than a copy that completes the migration for the data file.
pROCES Planning IP migration should take into account the order in which servers are to be moved. For example, one process can access several data servers. Each of the servers accessible in this process should be moved in the same basic period of time, so all of them are in their new places when the process is running next time. The complexity of the planning process is roughly equivalent to the number of servers and processes affected by movement.
If IP migration is small or isolated, the organization may decide to take a step during working hours. This decision can also be made when servers do not support critical mission applications. When migration affects only auxiliary applications, the organization has much more flexibility in planning. The organization can often plan critical IP migrations over weeks during working hours so that technology staff can work on these steps during normal working hours. This reduces the cost of such an IP migration because overtime is OMezené.
The domain name system (DNS) used by the Internet as its telephone book When searching servers has up to 48 hours to update a new server location; In many cases, however, the update occurs very quickly. Sometimes the web server address can be changed in the morning and DNS recognizes it early in the afternoon. In other cases, however, the change may not be recognized for at least 48 hours. The time period in which the change is recognized depends mainly on the amount of activity that occurred immediately before and during the change.
