ESM version mismatch


Were upgrading our SIEM however we have an inquiry if we can still ingest events from ERC of lower version (previous ver) than the ESM. WEre doing this to minimize downtime of event monitoring in our tenants. Once weve upgraded the ESM can we enable the auto-dl of events in the ERC of our tenant and wait for the appointed upgrade/downtime for the tenant. Will we still collect events from the ERCs even though our ESM is already upgraded?

Re: ESM version mismatch

Depends on the versions for example 10.4 to 11.x will not work because of the way the method has changed between the two. However, most 11.x to 11.x should work. I would not leave in the state for long. I would also note the receiver will still collect the events even if they cannot send to the esm.
