So far, I've seen only positive feedback on the call summaries both here on the Zeta mailing list & in the Zimbra Community forum (where the call summaries are also posted), so I'll keep using the same summary format unless someone suggests an improvement.<br></div><div><br data-mce-bogus="1"></div><div>According to what John H. shared with us on the call, he said that it's actually Zimbra 8.x that Zimbra 9 shares 85% of its codebase with, rather than Zimbra X. From everything I've heard about Zimbra X over the last year or so, I have the impression that Zimbra X is a complete re-write of the codebase. I think the re-write is something that Rene led, when he was with Zimbra, as a necessary step to change from the current architecture to the microservice Docker container model that X uses. So, that would suggest that going from Zimbra 8 to 9 will be more of an incremental upgrade, rather than a major upgrade that going from Zimbra 9 to X will likely be. John's comments seemed to suggest that the focus for Zimbra 9 is on improving both the end user experience & the Zimlet architecture for developers, while there are little to no changes for administrators in version 9.<br data-mce-bogus="1"></div><div><br></div><div>Thanks for pointing out the option to run both the new React UI & legacy UI in Zimbra 9. I overlooked mentioning that in the call summary write-up.<br></div><div><br data-mce-bogus="1"></div><div data-marker="__SIG_PRE__"><div><div><div><span style="color:rgb( 255 , 102 , 0 );font-weight:bold"><br>Randy Leiker (</span><span style="font-weight:bold"> <span style="color:rgb( 51 , 51 , 255 );background-color:rgb( 255 , 255 , 255 )">randy@skywaynetworks.com</span> <span style="color:rgb( 255 , 102 , 0 )">)</span></span><br><span style="color:rgb( 0 , 0 , 153 )">Skyway Networks, LLC</span><br><span style="color:rgb( 0 , 0 , 153 )"></span></div><div><span style="color:rgb( 0 , 0 , 153 )"><br data-mce-bogus="1"></span></div></div></div></div><hr id="zwchr" data-marker="__DIVIDER__"><div data-marker="__HEADERS__"><b>From: </b>"Marc Gadsdon" <mg@in-tuition.net><br><b>To: </b>"users" <users@lists.zetalliance.org><br><b>Sent: </b>Wednesday, February 19, 2020 2:53:10 AM<br><b>Subject: </b>Re: [Users] February 18, 2020 Zeta Alliance Conference Call Summary<br></div><div><br></div><div data-marker="__QUOTED_TEXT__">Hi Randy,<br><br>As always, thanks very much for writing up these summaries. Super useful.<br><br>> The Zimbra 9 back-end<br>> uses the same back-end as Zimbra 8 and is about 85% the same codebase. <br><br>I understood that the 9.0 backend contains much of the codebase as Zimbra X, but without all the container stuff. Come to think of it, I thought it was 85% but I also remember that being mentioned in relation to 8.8.x too, so now I'm a bit uncertain. Perhaps one to clarify on the next call, or we'll just have to be patient and wait for a release to investigate properly!<br><br>> The React UI is currently targeted<br>> for improving the experience for end users, while the administrative Zimbra UI<br>> remains the same as found in version 8. <br><br>One other key point we talked about, which I think people will be keen to know, is that the new React UI will be able to co-exist with the legacy UI and be used simultaneously - e.g. 1 browser, 2 tabs, each logged into the same mailbox.<br><br>Marc<br></div></div></body></html>
