Updating Sametime 12 to FP1. Not all customizations are kept
Upon suggestion from my friend Erik Schwalb of HCL, I upgraded to FP1 a Sametime12 server where I made some branding customization.
Contrary to what I wrote in my previous post not ALL customizations are kept.
If you made some branding, you will lose it. The directory /sametime-config will be deleted and replaced by a new one, so all the custom branding files in /sametime-config/web/branding will be gone.
Also, not all the settings in custom.env will be kept. If you applied branding adding, e.g.
REACT_APP_PRODUCT_NAME=RoB ST Server
those settings will not be kept.
To check which settings are kept, look in install.sh, you will see that the upgrade maintains the default ones, e.g SAMETIME_PROXY_HOST=st.company.com.
If you enabled Let’s Encrypt support in .env you will lose it as well, since the Let’s Encrypt TLS cert in /sametime-config/web/acme-certs/ will be gone.
Again, check install.sh to see which settings are maintained in .env
So, the suggestion I have is to copy the sametime installation directory (you read my previous post, right?) and then after the upgrade copy back the /sametime-config directory and check the files custom.env .env and docker-compose.yml
Thanks a lot to Eric Schwalb for pointing me in this direction, since I didn’t applied customizations at my customer site, I did not notice that some settings are not kept.
