Upgrade / Downgrade Guidelines
The RMX configuration, including users and passwords, should be backed up before
upgrading or downgrading.
Table 23-16 summarizes the system behavior with regard to passwords and certificates
when upgrading to or downgrading from this version.
Table 23-16

from old
version to new
version
On user login:
•
All
new
-
user
passwords are
hashed and saved using
SHA-256
.
•
Existing
user passwords remain
saved using the SHA-1 signature,
however:
•
On first login after the upgrade
the
SHA-1
hashed password is
automatically replaced with
SHA-256
hashed password.
Note:
After an upgrade to version
8.1.4.J
there will be still passwords
saved with the
SHA-1
signature.
In order not to rely on automatic
password signature conversion and
replacement, and to ensure
that the
system only has
SHA-256
hashed
passwords saved, the administrator
should:
Either:
•
Ensure that all the users login to
the system at least once to ensure
automatic replacement of
SHA-1
hashed passwords with
SHA-256
hashed passwords.
Or:
•
Delete and recreate all users.
The new version accepts certificates
issued with
SHA-1
hashing.
