+## Upgrade Instructions
+
+(Put this near the end.)
+
+1. The [Dataverse 6.10 release notes](https://github.com/IQSS/dataverse/releases/tag/v6.10) explained how to upgrade from Payara 6 to 7 but did not originally include the important step of migrating a setting for the number of seconds before a request times out. As described in [the guides](https://guides.dataverse.org/en/6.12/installation/config.html#http-request-timeout-seconds) you might want to shorten or lengthen this value. The default is 900 seconds (15 minutes). If you set it to an hour using the command from the guides (`asadmin set server-config.network-config.protocols.protocol.http-listener-1.http.request-timeout-seconds=3600`) you should see a line like this in your domain.xml file:
+
+   `<http request-timeout-seconds="3600" max-connections="250" default-virtual-server="server">`
+
+   See also #12543.
