## 2.2 OBX and Base artifacts compatibility

This topic provides the systematic instruction to perform OBX and Base artifacts compatibility.

OJET version compatibility:

The implementation team must ensure that the OJET version of the app shell used aligns with the OJET version present in the OBX tool.

Note:

As part of OJET upgrade some older libraries may not be supported. If consulting / implementation team is using any of the unsupported libraries for their customizations, compatibility issues may arise if the app-shell version they are using doesn't include those OJET libraries.

All the UI customizations/extensions are bundled into `extended-components` war which ultimately refer to the app-shell OJET libraries only.

Please find the compatibility matrix of app-shell OJET versions and OBX OJET versions below.

Table 2-1 OBX - Compatibility

OBX version | OJET version
--- | ---
14.7.0.0.0 | Appshell version xxxx (has 13.0.0 OJET version)
14.7.5.0.0 | Appshell version 9.5.0 (has 15.1.8 OJET version)
14.8.0.0.0 | Appshell version 9.6.0 (has OJET Version 17.xxx)
14.8.1.0.0 | Appshell version 9.6.0 (has 17.0.0 OJET version)
14.8.2.0.0 | Appshell version 9.6.0( has 17.0.0 OJET version)
