Maintance expires date for my Jira and confluence in May-04-2020 . We have scheduled date to upgrade on 16/may/2020 ( We cant changes this fixed upgrade date unfortunately ).
We wish to upgrade jira from 7.1.1 to 8.5.3 Enterprise version and confluence from 5.10.7 to 6.13 Enterprise version in windows . I want to do this upgrade without renewing Maintenance .
1 .Upgrading jira without valid license is never possible ?
2 .What would be the potential impact i could face ? and What are dis advantages ?
3 .If upgrade possible , Within how many days I should renew Maintenance license ?
4. Before Mainatance expires , If we do upgrade , What are the advantages ?
Thanks in advance .
