Markus and Volker,
Thank you and points awarded to you both- your prompt and relevant expert responses are very much appreciated!
I thought I'd follow up on the key point Markus made for other forum readers with the same question-
"You have to take into account that once you entered the copy phase (where the shadow system is built) no more transports may run into production (the TMS will be locked). That means that you'd have a full week without the possibility to do changes to the system."
The Upgrade Guide for SAP ERP 6.0 EHP4 SR1 ABAP specifically calls out "You may not perform any more transports into or out of the SAP system" after confirming Preprocessing Roadmap phase LOCK_PRE (ABAP Workbench Locking) or at the latest phase REPACHK2. As Markus points out once you confirm either Preprocessing phase above you will NOT be able to import production support transports so determine your business support needs timing carefully before confirming these key phases.
Volker's timeline comment to have at least a few days to resolve any upgrade uptime issues makes sense too- ultimately it is up to the Basis team to work with the business team to find the best compromise balance of "no transports while waiting for downtime" vs "having time to fix any upgrade process issues" when you have a firm production downtime date to meet.
Thanks again to you both for your expert insightful help 😆
