LTM sync when upgrading iapps

Question

Hi, we have a LTM pair running 11.5.1, HF7. We plan to upgrade one of the iapps to the latest version. One of my colleagues mentioned that he had run into LTM sync trouble after upgrading them. He was on ver 11.4. They had to call in support and reboot the standby unit in order for the devices to re-sync. This is scary !
I don`t have a test environment where i can test this iapp upgrade, hence reaching out to the experts. Will I be able to upgrade my iapps without any issues on the version that I am running on?&nbsp;

there is this issue: sol16460: Incremental synchronization may fail when an iApp application service is modified&nbsp;
There was an issue with a specific iApp (Citrix if I remember well) that contained a monitor with bad formatted strings. We solved that when upgrading to 11.5.1 HF7 (sol15977: Health monitor that contains certain characters in receive or send strings may cause configuration load failures)&nbsp;

ok thanks, any known issues for upgrading to the Lync_server_2010_2013v1.3-RC1 iapp?&nbsp;

Hi, there are no known issues, although you should at least be upgrading to the officially supported version, f5.microsoft_lync_server_2010_2013.v1.3.0.tmpl, which is out on downloads.f5.com. The RC1 version is an earlier release candidate of that same template.
