Pscellchange inter gNB

hi expert,

we have two 5g sites that PsCellChg_SR_InterGNB Intra Freq KPI from one site to another are around 30% and from another site to the target site is 99%. all definition and relation, external, x2,s1 link are ok. (All sector is around 40%)
there is no major alarm.
what other things should I check?

Pci conflict

There are only 2 5g sites. there is no PCI conflict here
