🆕 What's new

Release	Highlights (from AE's release notes)
EPIC 3.2.5 9/16/2026	Added: Transporter logs in the downloadable logs; startup check of the AE1/AE+ connection (logged); AE+ connection resiliency (keeps valid credentials during an outage, retries with backoff). Fixed: microphones not resetting after a non-paired alert; SIP config conversion error; CSV import not assigning teachers to rooms; LDAP Base DN spaces and SSL setting; SSO CSV email handling; badge status polling; Barionet stop-all error. New: loose routing for SIP outbound proxies.
MS-700 2.1.2	Fixed "screeching" in SIP audio; line-in audio now mutes when an HPN or SIP stream is active; fixed the up-to-4-second audio delay introduced in 2.1.1.
CZA-1300 / MS-775 / MS-720 1.0.12	Fixed log file downloads, which failed on the previous firmware.
ITC 219	Fixed random ITC shutdowns and phantom button presses / repeat alerts.
MS-600/500A/300B 1.2.4	MS-300B now reports itself as MS300B (it answered as MS500A). From this version on the firmware can't be pushed from EPIC.

📝

Tech note from AE: on Kiosks, turning off "Pull down to Refresh" is suggested to improve touch response (instructions are linked from the EPIC 3.2.5 release notes).

1️⃣ Check the version a server is running

Log into the EPIC server as an Administrator.
Click Settings on the left, then the System Settings tab at the top.
The EPIC version and serial number are in the bottom-right corner of the page (e.g. v2.5.4.1 S/N: 20XX-XXXXXX).

Settings › System Settings. The version and S/N are at the bottom right of the page (EPIC 2.5.4; school name and S/N redacted).

Settings › System Settings. The version and S/N are at the bottom right (EPIC 2.5.4; school name and S/N redacted).

2️⃣ Before you upgrade the server

Take a backup first: Settings › System Settings › Import/Export › Export Configuration/Backup. AE recommends this before every update.
Schedule it for a maintenance window, not during the school day.
Internet access: the EPIC server needs outbound internet access during the upgrade.
Download the file for the target version from the AE release notes page (.tar.gz.dat).

⛔

Check the upgrade path. Servers below 1.9 need a custom upgrade from AE and must reach 1.9.0.1 before going to 2.1+. Coming from before 2.5? Move notification recipients into Contacts after upgrading (see 📩 Changing Emergency Contacts, QR-AE-005). Editing events before that migration can lose event contacts. Going to 3.x from before 3.0: 3.0 is a major release with a redesigned home page; AE asks admins to review the EPIC Interactive Training Module and train staff first.

3️⃣ Upgrade the server

Log into the EPIC server as an Administrator.
Click Settings, then the System Settings tab.
On the sub-menu, click System Upgrade. It opens in a new tab.
Upload the .tar.gz.dat file. Wait for the upload to finish; the green Upgrade button becomes clickable.
Click Upgrade and wait for the green progress bar to fill again. The server reboots on its own (several minutes).

💡

Pro-tip: watch the clock. Leave the EPIC page open and watch the clock at the top. While the time is frozen, the server is still booting. When the clock jumps to the correct time and the seconds count up, it's ready. Refresh the page.

4️⃣ After the server upgrade

Go back to Settings › System Settings and confirm the version changed. If it didn't, contact AE Support.
Test everything: intercom, paging, bells, SAFE and any third-party integrations (AE's recommendation after every upgrade).

5️⃣ Update device firmware

EPIC holds a base firmware for each device type. Device firmware files come from the device's AE release notes page (e.g. MS700-FW-2.1.2.tar.gz.dat).

Go to Settings › Update.
Click Manage Current Firmware, browse to the file from AE, enter the version, and click Save. This makes it the new base firmware.
MS-700, MS-x00 and CZA-1300 family: the devices check EPIC every day and on boot. To update right away, reboot the devices (Settings › Reboot). MS-600/500A/300B on 1.2.4+ can't be pushed.
ITC1 / ITC2 and other pushable devices: pick the device-type tab, select the devices, and click Update Selected Devices. This can take a few minutes on a large site.
Check each device type's tab afterwards. A firmware-update icon on a single device in the device list means it's still out of date.

⚠️

MS-450 and MS-500: the audio amplifier has its own firmware, separate from the network firmware, and it can't be updated over the network. It's done through the mini/micro-USB port on the device (AE Admin Manual).
