As a rule, all QueryGrid Managers in a cluster must be upgraded to the same version within a rolling upgrade. In specific cases where exceptions to this rule are unavoidable, the following QueryGrid Manager versions can be clustered together:
| QueryGrid Manager Version | Compatible QueryGrid Manager Version |
|---|---|
| 3.00.00.00 | 3.00.00.00 (not compatible with QueryGrid 2.x) |
| 3.01.00.00 | 3.00.00.00 (not compatible with QueryGrid 2.x) |
| 3.02.00.00 | 3.00.00.00, 3.01.00.00 (not compatible with QueryGrid 2.x) |
| 3.03.00.00 | 3.00.00.00, 3.01.00.00, 3.02.00.00 (not compatible with QueryGrid 2.x) |
QueryGrid versions 3.00.00.00 and later do not support clustering with QueryGrid 2.21.00.00 and earlier.
