Info about NSU PRI Upgrade database from ICP 9.0 >> MCD 4.0 SP4

[steve75]

Hi, i need to upgrade Mitel 3300 Mxe with 2 PRI connected into 3300 Universal NSU.
The correct procedure says that i need to upgrade the 3300 with full install from 9.0 to MCD 4.0 SP4.
After upgrade the NSU will upgrade automatically with the new firmware.
Questions: when the 3300 Mxe upgrade the Universal NSU with the new firmware, the Database PRI into NSU is deleted?

Is there a way to connect sull'NSU before upgrading the firmware to make a database backup of the ICP version 9.0 and then load DB file and a convert the database to version 4.0 SP4 MCD with IMAT ??
Any suggestion is appreciated!
Thanks in advance!

I would assume that the DB would stay. You should be able to backup and restore the NSU DB, but if not there shouldn't be that much in there. Unless you have a lot of CPN sub entries, then manually entering (if necessary) may not be too fun.

The database stays, I have done several upgrades with NSU's and never had to even log into an NSU afterwards.

Be aware that is can take some time for the NSU to update, be patient, it takes much longer than an ASU to update in my experience.

I've done some nsu upgrades where you had to upload a new database for it to come back up

You may need to upgrade your database first with IMAT if the version of the NSU (IMAT) is different.  Load the IMAT database on your laptop first with IMAT and it will tell you if you need to upgrade.  Read the release note too....

No change to the IMAT DB between 9.0 and MCD 4.0, I've done the same upgrade myself with no issues.

That being said, always make sure you have a current backup of your IMAT DB's, just in case.
