Yes, The Flare will need to be upgraded before and after you come up as a CX4 running Release 29 you can upgrade to Release 30 . A code upgrade can take about 1 and a half hours depending if frumon code has to be upgraded might take longer
Hi,  If we opt for inplace upgrade from CX3 to CX4, do we need to upgrade the existing FLARE 26 running on CX3 ?  This is because DELL consultanat mentions that we have to take extra time to upgrade FLARE 26 to FLARE 29 before we can replace the CX3 DPE to CX4 DPE.  Then we can upgrade from FLARE 29 to FLARE 30 for CX4.  Besides, usuaully, how long to upgrade the FLARE if required ?  Thanks  Message was edited by: TonyJK
