In June 2023 we published the following Support Tip that contained maintenance which we recommend customers install prior to upgrading to the ZMF 8.3 release:

 Support Tip: Recommended maintenance for customers running or upgrading to ChangeMan ZMF 8.3  

This was followed in August 2023 with the following article detailing additional changes that we recommend customers install prior to their upgrade:

 Support Tip: Further maintenance recommended for customers running or upgrading to ChangeMan ZMF 8.3  

Recently a further issue has come to light that, again, we recommend customers resolve prior to upgrading the product. This is critical for customers that use ‘Save Staging Versions’ (SSV) functionality:

SSM8.6.1.003/OCTCR46A339001 Users receiving CMN8711I errors after upgrade to ZMF 8.3

As always, the same notes, caveats, etc., as before apply to the above recommendation. Namely:
a. All of the issues listed above, and their associated hotfixes, apply to the ZMF 8.3 release ONLY. These hotfixes must not be requested or applied to anything other than ZMF 8.3 subsystems. 
b. Other known issues and further hotfixes do exist for the ZMF 8.3 release. However, those listed above are the ones assessed at time of publication of this Support Tip (i.e. 27th September 2023) as being particularly pervasive or troublesome if they were to be missed during upgrade testing.
c. Further Support Tips may be published in future should additional problems/fixes in the ZMF 8.3 release be assessed as being equally potentially problematic.
d. To request any of the hotfixes listed above please open a new case, one per hotfix, asking that the hotfix be supplied.
e. Similarly, should you hit any other issues during your ZMF 8.3 testing or upgrade then, again, please open a new case and we will be happy to assist.
