Important:

The upgrade procedure for systems that use Avaya-provided Linux is different from the upgrade procedure for systems that use customer-provided Red Hat Enterprise Linux. For Avaya-provided Linux upgrades, you must download the supported Avaya-provided Linux from the AvayaSupport site.
Note that as with any upgrade, the OS of the system must meet the requirements of the new version of Experience Portal. If it does not, then the OS must also be upgraded.

	Note:
	Experience Portal upgrades or migrations from on-premise deployments to cloud deployments arer not supported in AEP 8.1.

For an Experience Portal system that includes multiple zones, Avaya recommends that you upgrade Experience Portal on a zone by zone basis. That is, you upgrade the servers in one zone before upgrading the servers in a different zone. Once the zone is fully upgraded, the zone is fully operational. However, Avaya recommends that once you start upgrading a system, upgrade all zones as soon as possible to avoid any compatibility issues that might occur.

To support an upgrade without service interruption, the system must have more than a single MPP.

When upgrading with a single MPP, there is service interruption but there no loss of data.

When upgrading with multiple MPPs:

The following services are not interrupted:	There following services are interrupted:
Inbound calls Outbound calls Inbound email messages Outbound email messages	EPM web interface Report data collection SNMP Agent Telephony port reallocation Inbound SMS messages Outbound SMS messages

Experience Portal supports upgrades on HP DL 360 G9 and Dell R630 servers that are provided with Experience Portal R6.0, 7.0, 7.1, or 7.2.
