Thanks Viswanath Sir!
A server is in production and we won't touch it. We have got one more set-up and as mentioned earlier it is a 3-tier architecture.
Migrating as it is (with current moodle 1.9.4) from production to 3-tier is easy but now we want to have higher version of PHP and of course MOODLE. If any higher version of PHP (lets say 5.4.10) and moodle 1.9.4 are compantible then we think we will not upgrade moodle. What is the experience of moodlers here?
And if managerial decision compells us to upgrade MOODLE also then there is no way. We will have to upgrade. I have read many horro stories on this forum about issues faced by moodlers in version upgrade. As suggested in this forum, we can plan for 1.9.19+. Any other views/opinions are invited.
Vaulnerability Report- Our secuity team conducts security testing and shares report. The application can be exposed to internet only after closing VA issues.
Note- Our existing moodle installation was customised for certain conditions, situations, etc. We have a theme also.
Thanks and Regards!
