I am currently using Invoice Ninja v4 Self Hosted on Debian and I know that support for v4 is coming to an end both having to do with PHP and larval. I am working on making the move now. I see that it’s recommended to use Ubuntu to host v5. I also see that there needs to be a new FQDN to proceed as well.
That’s all fine but I was wondering where that leaves my Debian system running v4? Do I have to keep that system running even after the upgrade indefinitely? Wouldn’t that defeat the purpose of the upgrade and security issues with v4?
My apologies if I am missing something here and thanks in advance for your help.
