In the process of upgrading several DECmcc systems that share a DECdns instance repository, I've discovered a situation where V1.1 and V1.2 systems cannot retrieve information stored by a T1.3.0 system. I'm starting with a VMS system running DECmcc V1.1 (system A). This system is also a DECdns server. The second system (B) runs ULTRIX 4.2, DECnet/OSI 5.1, and DECmcc V1.2.3, and uses system A's nameserver. I installed DECmcc T1.3.0 on a third system (C) running VMS, and using A's nameserver. This worked fine - I was able to open the existing domains, etc. Next I decided to restructure the namespace, and move the nameserver from system A to C. I used the MCC_DUMP_NS.COM procedure to extract the entire instance repository, created a new clearinghouse on C and used DECmcc T1.3.0 on system C to set up and reload the namespace. Now only system C works. On both system A and B I get the message "invalid entity structure" whenever I try to open a domain that has any members. Have there been any changes in the way DECdns is used in the new version? Is there something I can do to recover from this disaster short of rebuilding the entire namespace from the V1.2 system? - Andy

RE: .0
Thanks for finding the problem.
There were some changes in storing AESs in ILV-format in T1.3.
This change prevents DECmcc V1.1 users from seeing entities in DECdns
which are registered using DECmcc T1.3.
The users who have to stay with DECmcc V1.1, we suggest that the
domains and other entities (e.g. Vitalink AM) should be created/registered
using V1.1. In other words, do not use domains created by DECmcc T1.3.
To summarize compatibilities among different versions of DECmcc:
1. DECmcc V1.3 (or T1.3) can access V1.3, V1.2, and V1.1
information.
2. DECmcc V1.2 can access V1.3, V1.2, and V1.1 information.
3. DECmcc V1.1 can access V1.2, and V1.1 information, but cannot
access V1.3 information in DECdns.

P.S. This restriction will be included in the Field Test Release Notes.
