Currently there are three types of switches for Mimix. Planned Switch, Unplanned Switch, and Virtual Switch.
This is a great way to test that your data is being replicated and your applications are functional. This requires no source downtime which allows you to complete this testing when you have your whole team available. The way this works is that once you virtually switch, Mimix keeps track of any changes made on the target during testing and will roll back all changes once you are completed and switch back. This is a great time to complete destructive testing since the data will be rolled back to before the switch. I recommend completing this type of switch three times a year.
This is a full switch procedure that is controlled. You are able to switch Mimix when you know that the data groups are caught up and you have access to both source and target. This will give you the ability to not just test your data but also your network connections. This is important to complete yearly and will take a small downtime on source for the switch. This will replicate data from your testing to replicate back to your source, so you want to make sure any changes are ok to go back to the source.
This is a full switch procedure if your source system goes down and you have no access to it. This will switch the data groups to the target so you can prepare to replicate back once your source machine is back online. You do not want to have to run this type of switch and hope you do not have to execute. This is why you have the protection of Mimix to be able to switch over in case of source outage.
So in closing, if possible you want to test your environment quarterly. Three virtual switches and a planned switch. This will make sure you can sleep at night knowing you are protected from an outage.
