Hi Ana,

When you say your server has changed IP, has the machine name and PI server ID remained the same?
Do you have any control over your clients PISDK connections? e.g. via a central mechanism that configures the clients connections?

If you have a different PI server name then you can add a PISDK alias for you new server name of your old server name so your clients do not have any outage. In Datalink your reports would still run fine, only when your try to reconfiure the reports you will only be able to use the new PI server name.
