Alert: Patch 28553832(11g R2 Extended Support patch) need apply upgrade to 19c

Direct Upgrade to Oracle Database 19c的版本有11.2.0.4,12.1.0.2,12.2.0.1,18c. 在最近11G (11204)升级19C的方案测试时遇到了上面的错误, 是不是很惊喜?在GI升级19c时需要检查patch 28553832是否安装,而且不允许跳过。这个从Patches to apply before upgrading Oracle GI and DB to 19c or downgrading to previous release (Doc ID 2539751.1) 可以确认。
