The current subject matter provides a method to upgrade an individual tenant by moving the individual tenant from a source computing system that implements an older software version to a target computing system that implements a newer software version. The movement of the individual tenant incorporates a movement of customer-specific data associated with the moved tenant. Instead of just upgrading a same multi-tenancy computing system implementing the tenant that needs to be upgraded, a new (target) multi-tenancy computing system implementing a newer software version is installed such that this tenant can be moved from the (source) multi-tenancy computing system to the new (target) multi-tenancy computing system. The data associated with the moved tenant is adjusted to new structures associated with the newer software version.

Tenant move upgrade

Described herein are systems and methods for three phase exception handling ensuring high availability of services. Via unified application program interface (API), one or more inspector instances are observing the behavior one or more services. The three phase exception handling is triggered upon observing an abnormal service behavior. Phase one comprises executing one or more commands from the unified API by the one or more inspector instances in attempt to resolve the abnormal service behavior and notifying a centralized inspector engine. Phase two comprises executing one or more predefined rules according to the current service state by the centralized inspector engine in attempt to resolve the abnormal service behavior and notifying an administrator. Phase three comprises abnormal service behavior analysis by the administrator and executing customized by the administrator rules to resolve the abnormal service behavior.

Ensuring high availability of services via three phase exception handling

A method includes generating at a client, operating on a user computer, a URL request having URL parameters according to a representational state transfer (REST) protocol, transmitting the URL request from the client to a gateway, which is operating on a server computer, and extracting via the gateway the URL parameters according to the REST protocol. The method further includes generating via the gateway a query for hosted content identified by the URL parameters, transmitting the query to the database, generating a search report for the query, and transmitting the search report from the database to the gateway. The method further includes encoding via the gateway the search report in an XML representation according to the REST protocol, and transmitting the search report in the XML representation from the gateway to the client where the client decodes the search report in the XML representation via the REST protocol for display.
