Netweaver JAVA 7.4 / ADS

Hi experts,

We are planning to migrate our central Netweaver JAVA 7.01 system running ADS to a Netweaver JAVA 7.4 just to keep it update and on a new version. There are any incompatibility you guys foresee between the new ADS running on 7.4 and other ECC 6 (EHP6 SP9 or SP4) ABAP systems?

Regards,

Fernando
