After a couple of goes at this – I finally found time to get this working.
I found that good old scripting worked beautifully – kudos to Neil Pang for acme.sh – it’s a work of art.
Installation instructions are easy; there’s a great walkthrough for Apache2.
A little testing with CloudFlare (turning off their re-write and dynamic SSL support) – and it’s working a treat.
Finally got this all working across multiple servers, websites and vhosts.
Again the SLES team made this really easy – using zypper and the online update repositories. Less than 15 minutes per server – and a single reboot.
Documentation is at https://www.suse.com/documentation/sles-12/book_sle_deployment/data/sec_update_migr_zypper_onlinemigr.html
Accept the recommended upgrade – and read and accept the EULA – and you’re away. For me 240MB download, 156 packages, 10 minutes of install, one reboot.
