→ Applies to: SynetoOS 6.x

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

Step 2. Get root privileges

sudo su -

Step 3. Check the release channel

config fir show

EXAMPLE OUTPUT - GA (General Availability)

[root@srvsyn02 tmp]# config fir show 
SynetoOS Version: 6.0.0
Release Channel: ga
System ID: 3358af973b6515a48c34463247ab7841
Serial Number: SY2300000000

EXAMPLE OUTPUT - RC (Release Candidate)

[root@srvsyn02 tmp]# config fir show 
SynetoOS Version: 6.0.0
Release Channel: rc
System ID: 3358af973b6515a48c34463247ab7841
Serial Number: SY2300000000

Step 4. Change the release channel between RC (Release Candidate) and GA (General Availability) as needed

sudo sed -i -E 's|("upgrade_channel":[[:space:]]*")rc(")|\1ga\2|; t; s|("upgrade_channel":[[:space:]]*")ga(")|\1rc\2|' /etc/syneto-upgrade-channel.json

The command switches the release channel: if the current channel is RC, it changes to GA; if it is GA, it changes to RC.
