lock development during EHP Update

Hello all,

we are doing a EHP6 update on our ERP System.

We have upgraded our development system already.

Now we are going to update our quality system. Now my question.

We are in the phase "preprocessing". Now the SUM asks for lock the development enviroment.

Does this mean, that we are not able to make emergency transports to the quality system and also later to the production system when it is in this phase ?

Thanks for your help.
