Onboarding SRX to MIST Cloud with config managed only from CLI and not from the MIST Portal.

Requirement is to preserve the config on SRX while adding it to the MIST cloud.

If a SRX already running with some config and needs to be added to the MIST Cloud without overriding the existing config, then we can do it by following the below step by step procedure:

• Make sure that the SRX has Internet Connectivity and correct route to reach the MIST cloud. (ping 8.8.8.8, show route 8.8.8.8)
• Make sure the SRX config does not have any MIST related config lines. (show configuration | display set | match mist)

Note : If there are any MIST config found, then the SRX could already have been added to an ORG. Check and identify the ORG where it is added and delete/release it from there if required. Else, continue with the below steps.

• Login to the MIST UI and go under Organisation and then under Admin, select Inventory.
• On the top right corner, click on "Adopt WAN Edges"
• Copy the CLI Commands and execute them on the SRX.
• Commit the changes for 15 minutes. (commit confirm 15)

At this state, SRX will try to dial in to the MIST Cloud. Check "show system connection | match 2200". We should see TCP ESTABLISHED connection with the MIST Cloud IP.

• Check under the Inventory > select the SRX and under More select "Assign to site".
• On the next screen, please uncheck the option "Manage configuration with Mist" under Manage Connection.

• Then proceed by selecting "Assign to site"

We are done with the setup and the SRX should come UP as Connected on the MIST UI with all the config intact.
