We have 20application based on Angular(1)JS, Spring3.x, SpringBoot and OracleForms. Currently they are hosted on-premise datacentre with Java7 and Oracle11G.
Infra recommendation is to put on AWSCloud and Oracle18C. From application point of view will upgrade apps. to Spring5.x and SpringBoot2.1.x But I have below questions -
1)What JDK should we use. How long will Java8 based app. work without being deprecated. 2) DO we need to migrate Angular(1)JS to Angular2/above. We are not looking for any performance/feature enhancements here.
