I need to upgrade existing version (4.2) to 5.X.Please assist on following key points as below:
1. Is there any separate guide/document just for upgrading version of ThingWorx?
2. Can I upgrade it to 5.3 (latest) directly? will it cause instability in my application?
3. If I cannot upgrade it to 5.3 directly,then do I need to do it like 4.2 to 5.0 then 5.0 to 5.1/5.2/5.3 ?
Thanks in advance.
Go to Download section. Under leftmost big "Download" button there is a link to Installation and Configuration document. "<a class="widget-link textsize-normal" href="https://twc.thingworx.com/Thingworx/FileRepositoryDownloader?download-repository=ThingWorxPublicRepository&download-path=%2FDocumentation%2F5+0+Install+and+Configuration.pdf" target="_blank" style="margin: 0px; padding: 0px; filter: none; color: rgb(57, 108, 191); cursor: pointer; height: 20px; width: 135px; line-height: 20px; display: inline !important; background-image: url(https://twc.thingworx.com/Thingworx/Common/extensions/Linkv2_ExtensionPackage/ui/linkv2/images/clear.png); background-attachment: scroll; background-size: initial; background-origin: initial; background-clip: initial; background-position: 0px 0px; background-repeat: repeat;">Installation & Configuration</a>"
On page 5 there is subtitle "Upgrading when there are schema changes". Take a look at this. Also ensure that you've read Migration FAQ in this document.
I'll go with upgrading 5.3 directly. But make sure you have backup. Just in case.
