OVF generated with older versions of ovftool(less than 4.2 ) uses SHA1 for manifest file which works fine on Vcenter 6.0 but not on vcenter 6.5. Same with OVF generated with 4.2 version of ovftool uses SHA256(can be changed) for manifest file which works fine on Vcenter 6.5 and not on 6.0 .
To summarise SHA1 works on 6.0 but not on 6.5 and SHA256 works on 6.5 but not on 6.0 .
Is there a way to generate common OVF which works on both 6.0 and 6.5 ?
