R12.1.3 to R12.2.5

[Sri]

Dear erman,

1.Do we need to run tums utility on existing R12.1.3 instance before upgrade to R12.2?

2.Where can we find high priority patches to apply on existing r12.1.3?

3.Is it required to run SLA preupgrade program when upgrading from r12.1.3 to r12.2.5?

4.From you experience,can you plz let us know how many patches you would have applied for upgrade from r12.1.3 to R12.2(approx)?


Thank you for the support

4 questions in 1 issue :)
next time ask them seperately.

1)tums is used for the upgrade from 11i only
2)Check this note -> Identifying the Latest Critical Patch Update for Oracle E-Business Suite Release 12 (Doc ID 2484000.1)
3) Check this note -> R12 FAQ for the SLA Upgrade: SLA Pre-Upgrade, Post-Upgrade, and Hot Patch (Doc ID 604893.1)
4) what a question :) it depends. You need to analyze it yourself.
