Customers upgrading from older versions of OSCE need to upgrade their standalone SPS servers in order to ensure compatibility with the OSCE servers and client machines.
SPS 3.x is backward-compatible with OSCE 10.6.
OSCE 11.0 and XG use a newer iCRC module which is only compatible with SPS 3.0 and later.
| SPS 2.6 | SPS 3.0 | SPS 3.1 | |
| OSCE 10.6 | Yes | Yes | Yes |
| OSCE 11.0 | No | Yes | Yes |
| OSCE XG | No | Yes* | Yes |
* The Predictive Machine Learning feature in OfficeScan XG only works with SPS 3.1.
With this in mind, upgrade the SPS servers before upgrading the OSCE server and client machines.
