If you are deploying device images (pictures) via the Extreme Management Center
server, they are saved in the
appdata\VendorProfiles\Stage\MyVendorProfile\Images\ folder.
4.2 Important Upgrade Considerations
Extreme Management Center 8.5.x supports upgrades from Extreme Management
Center version 8.3.x or 8.4.x. If you are upgrading from version 8.1 or earlier of
NetSight/Extreme Management Center, you must perform an intermediate upgrade. For
example, if you are upgrading from NetSight 8.1, you must first upgrade to the latest
Extreme Management Center 8.3 or 8.4 release, then to 8.5.1.
IMPORTANT:
When performing an upgrade, be sure to back up the database prior to
performing the upgrade, and save it to a safe location. Use the
Administration > Backup/Restore tab to perform the backup.
l When upgrading the Extreme Management Center server, ExtremeAnalytics
engine, or ExtremeControl engine to version 8.5.1, ensure the DNS server IP
address is correctly configured.
l When upgrading to Extreme Management Center version 8.5.1, if you adjusted the
Extreme Management Center memory settings and want them to be saved on
upgrade, a flag (-DcustomMemory) needs to be added to the
/usr/local/Extreme_Networks/NetSight/services/nsserver.cfg
file.
For example:
-Xms12g -Xmx24g -XX:HeapDumpPath=../../nsdump.hprof -
XX:+HeapDumpOnOutOfMemoryError -XX:MetaspaceSize=128m -
DcustomMemory
l If your network is using ExtremeAnalytics or ExtremeControl engines, Fabric
Manager, or another add-on feature, you must first perform the Extreme
Management Center upgrade to version 8.5 and then add the feature.
l If you are running Data Center Manager (DCM), a Mobile Device Management
(MDM) integration, or other ExtremeConnect or Fusion integration with Extreme
Management Center, or are accessing Web Services directly or through
ExtremeConnect, you need to install an Extreme Management Center Advanced
(NMS-ADV) license. Contact your Extreme Networks Representative for
information on obtaining this license.
