<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m going to upgrade form 8.3.11-2 to 8.3.15-2.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Just a routine question. Is there any issue with running one node as 8.3.11-2 and the other as 8.3.15-2 for a few hours (like maybe 12 hours)? I want to upgrade the secondary system and let it run for a while, and then failover and upgrade
the primary late tonight, etc. Just curious if there would be issues with replication, etc., while in that mode.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks!<o:p></o:p></p>
