Coexistence with Previous Releases
This section describes ELS 7.2 coexistence and compatibility.
SMC 7.2 Coexistence
SMC 7.2 is compatible with the following software releases:
- HSC/VTCS 7.2 on the same host
- HSC/VTCS 6.2, 7.0, 7.1, and 7.2 on a different host
HSC/VTCS 7.2 Coexistence
HSC/VTCS 7.2 is compatible with the following software releases:
- SMC 7.2 on the same host
- SMC 6.2, 7.0, 7.1, and 7.2 on a different host
- ExPR 6.1 only
Compatibility PTFs
SMC 7.2 is completely compatible with HSC 6.2, 7.0, and 7.1 (with compatibility PTFs listed below) running on the same or different host. In addition, SMC 6.2, 7.0, and 7.1 are completely compatible with HSC 7.2 running on the same or different host.
Before attempting to start ELS 7.2, ensure that the following compatibility PTFs are installed on the down-level releases that share the CDS:
Table 1-2 Compatibility PTFs
| Product (FMID) | Compatibility PTF |
|---|---|
| SMC 6.2 (SMC@620) | N/A |
| HSC 6.2 (SOS@620) | LF620GW |
| VTCS 6.2 (SWS@620) | N/A |
In addition, it is strongly recommended to obtain the latest service (including HOLDDATA) for the down-level host systems. The suggested method of implementing ELS 7.2.0 is:
- Install the latest service on production hosts.
- Install ELS 7.2.0 on one ore more test hosts.
- Test and verify ELS 7.2.0 on the test hosts.
- Schedule the roll out of ELS 7.2.0 to production hosts.
