Have a good start:

glibc is zstd-compressed, but the newer rpm that can understand the format requires a newer glibc... it all needs to be unpacked with a second machine to break the cycle.

Then, "%__db_backend bdb" needs to be replaced with ndb. The newer rpm is prone to truncate the entire rpm database if it has to do any writes and that value is still on bdb. (Found out the hard way, but luckily I had /var/adm/backup/rpmdb)

Using the unmanaged rpm, install the managed rpm & glibc (and possibly zypper too).

(may need to add a few more, like liblua5_4, libselinux1, libsolv-tools, libzypp, zypper, ..)
I did require a --nodeps on a rather extended call as deps grew fast when python2 packages were involved.

Once done, both rpm and glibc are new and it's back to standard business:
first» zypper dup The following product is going to be upgraded: openSUSE Tumbleweed 20181015-0 -> 20210311-0
8800+ packages got updated One learns to value the speed of more modern machines :) Anyway, several hours later I had an up-to-date old HP EliteBook 8560p to be used by my son. (running kernel 5.11.6)
