First Claim
1. A non-transitory computer-readable medium containing instructions to configure a processor to perform a method, the method comprising:
- copying a source application server to form a shadow application server, the copying including copying a repository table and a customizing table to form a shadow repository table and a shadow customizing table;
implementing an upgrade at the shadow application server, the upgrade including table structure definitions for the customizing table and at least one application table, a content for the repository table, and content for the customizing table, the upgrade applied to a first synonym of the shadow repository table and a second synonym of the shadow customizing table, the first synonym enables the shadow application server to connect to the shadow repository table, when the upgrade is being implemented, and the second synonym enables the shadow application server to connect to the shadow customizing table, when the upgrade is being implemented, wherein only a portion of the upgrade is deployed to the first and second synonyms and only a portion of tables in the upgrade is copied to the shadow application server; and
switching to the upgrade by renaming the shadow repository table and the shadow customizing table to identifiers corresponding to the repository table and customizing table of the source application server.

Abstract
The subject matter disclosed herein provides methods and apparatus, including computer program products, for upgrading software. In one aspect there is provided a method. The method may include copying a source application server to form a shadow application server, the copying including copying a repository table and a customizing table to form a shadow repository table and a shadow customizing table. Moreover, the upgrade may be implemented at the shadow application server. The upgrade may be applied to a first synonym of the shadow repository table and a second synonym of the shadow customizing table. The first synonym may enable the shadow application server to connect to the shadow repository table, when the upgrade is being implemented. The second synonym may enable the shadow application server to connect to the shadow customizing table, when the upgrade is being implemented. The method may also include switching to the upgrade by renaming the shadow repository table and the shadow customizing table to identifiers corresponding to the repository table and customizing table of the source application server. Related systems, apparatus, methods, and/or articles are also described.
