Coexistence with Previous Releases
This section describes ELS 7.2 software coexistence and compatibility.
SMC 7.2 Coexistence
SMC 7.2 is compatible with the following software releases:
- HSC/VTCS 7.2 on same host
- HSC/VTCS 6.2, 7.0, 7.1, and 7.2 on different host
- MVS/CSC 7.2 only
HSC/VTCS Coexistence
HSC/VTCS 7.2 is compatible with the following software releases:
- SMC 7.2 on same host
- SMC 6.2, 7.0, 7.1 and 7.2 on different host
- LibraryStation 7.2 only
- ExPR 6.1 only
ELS Compatibility PTFs
With proper compatibility PTFs, ELS 7.2 can share a CDS with any previous ELS or HSC release beginning with HSC 6.2.
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 ELS Compatibility PTFs
| Product (FMID) | Compatibility PTF |
|---|---|
| HSC (VM) 6.2 (SMS6200) | L1H16N6 |
| HSC (MVS) 6.2 (SOS6200) | L1H16N7 |
| ELS 7.0 (SSEA700) | L1H16N8 |
| ELS 7.1 (SSEA710) | L1H16N9, L1H172A |
Note:
- All ELS software running on the same host must be at the same release level.
- SMC 7.2 is completely compatible with HSC 6.2, 7.0, or 7.1 (with compatibility PTFs listed below) running on a different host.
- SMC 6.2, 7.0, and 7.1 are completely compatible with HSC 7.2 running on a different host.
In addition it is strongly recommended that you obtain the latest service (including HOLDATA) for the down-level hosts systems.
The suggested method of implementing 7.2 is:
- Install the latest service on production hosts.
- Install 7.2 on a test host(s).
- Test and verify 7.2 on test host(s).
- Schedule the roll out of 7.2 to production hosts.
