Bi 4.1 Upgrade - promotion mgmt from sp 5.3 to sp 3

Hello,

We are planning to upgrade our dev systems from BI 4.1 Sp3 to BI 4.1 Sp5. As we have  lot of developments going on in dev system with tight schedule,  can we promote the contents ( reports) on BI 4.1 Sp 5 dev systems to  BI 4.1 SP3 Quality and prod systems ?

Upgrading Q and P systems to Sp 5 may take a while ,I am checking the possibility promiting the contents without impact between SP5 and SP3 systems.

Thanks in advance for your advise !
