Also, you're DB won't be aligned with the IP - changing the IP doesn't change the IP that gateways try to fetch policy and send logs, it's the IP in SmartConsole and for every CMA it has another IP.
To be clear,I won't change ip.
I will use the same ip and hostname of the old Primary MDS so I should avoid all the problem related to changing ip/hostname.
I will change the ip of the OLD mgmt only for an SSH access to move the log
b. If you have much logs I would try to configure retention that answer your needs - might lower the amount of storage you use for logs. Also mind the indexing policy
I can't , the retention is configured as the customer asked,and so the indexing policy
c. You can move the logs to the server after the installation. The issue - they would need to be re-indexed. Re-indexing that much logs may take time and resources
the indexed log are less than 11 TB , is not a problem to manual reindex them , we index the last 15days for each CMA, but the customer want to store the old log on this machine
