Answers to frequently asked questions about upgrading ArcGIS Maritime server are provided below.
If I have a multimachine server deployment, do I need to upgrade each machine?
Yes, all machines in the multimachine deployment must be upgraded to the same version of ArcGIS GIS Server and the Maritime server extension.
Do I need to uninstall a previous version of Mapping and Charting Solutions before installing the Maritime server extension?
No, if you already have Mapping and Charting Solutions installed, the Maritime server extension setup will automatically upgrade it to ArcGIS Maritime 11.4. After the upgrade, you will only see the ArcGIS Maritime 11.4 server extension in your list of programs.
Do I need to back up anything before installing the Maritime server extension?
Do I need to stop my GIS services and ArcGIS Server before installing the Maritime server extension?
No, the setup restarts ArcGIS Server after the installation.
If I upgrade to ArcGIS Server 11.4, do I also need to upgrade my Mapping and Charting Solutions?
Yes, the version of the Maritime server extension must match ArcGIS Server. You cannot run mismatched versions of software. When you upgrade, you will no longer see Mapping and Charting Solutions; the ArcGIS Maritime server extension will appear in your programs list instead.
