I have recently inherited an ELK stack 1.3.2/1.4.2/3.01 which will be moved to new platforms and upgraded at the same time. Is there any documentation around upgrading something so old ?
Also, I'd want to remove as much old data as possible, so is there a setting in the old versions of the software that will allow me to 'age-out' some data ?
I've tried to find the documentation for these early versions but it seems to keep keeping to the latest version so I'm not sure if the information is correct.
Thanks in advance,
