Currently the instance is pointing to disk c: but for space and growth we need to point to disk d: Is this possible? 1-. What steps should I execute to do it in case it is positive? 2-. If possible, do I lose historical data?Thanks in advance for what you can help us
You don't indicate what database you are using.
Regardless, the only thing that cares where on the file system the database is, is the the database server. So, just use the tools for your specific database technology to move the files.
MS SQL for instance supports having the files pretty much anywhere - so you can use the space on C: and when you're full on C: you can add files on D:. In fact, MS usually recommends that you put log and data files on different physical devices anyway. Or offline the database, move the files, edit the database to reflect the new location, then online the database.
And I think that your picture is likely wrong - usually the primary hub has most of the active connections to the database - that is unless the "proxy server" is a network device of yours and not a UIM device.
