upgrade jira 7.13 to jira 8.13 and differences in classes

[Maria Luisa Izquierdo Muñoz]

we have upgraded from Jira 7.13 to Jira 8.12 and we are using script runner. When reviewing the scripts in the pre-production environment already migrated, we see that the ComponentManager class and ComponentAccessor class have deprecate methods in the new version, what methods replace the old ones?
