Hello Experts. Quick question, will exchange 2013 from cu15 to cu19 upgarde fail if i did not extend the schema, prepare AD, and domain. I ask because i did run the commands and all completed successfully, but the schema version has not updated in ADSI edit, so i'm worried it may not have completed successfully. <br />
<br />
It will be a good test if CU 19 upgrade fails, as that will let me know of any replication issues. This is for my test env. I ran repadmin with /replsummary, /queue, and /showrepl, and i saw no errors. <br />
<br />
I did find an article that stated the schema version does not change with cu19, it remains the same as before, so how can i check if it updated.<br />
<br />
Please let me know. Thanks in advance
